Podcasts about Arecibo Observatory

On May 5, 2014 when I discovered 2014 JO25 with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona it was the brightest, fastest asteroid I had ever seen. In April of 2017, 2014 JO25 returned to come within 1.1 million miles of us at 21 mi/s. This rare, very close approach by an asteroid, of 2014 JO25's size allowed scientists at NASA's Goldstone Solar System Radar in California and the National Science Foundation's Arecibo Observatory in Puerto Rico to obtain radar images of it. Amazingly these images showed that what we had observed as a solitary moving point of light and had assumed to be a single asteroid is actually two asteroids in contact with each other. This tight pair rotates about a common center of gravity about every 5 hours which in turn orbits the Sun in about three years. 41 days before its encounter with Earth, this tight pair was closer to the Sun than the planet Mercury.

On 9 January 1992, astronomers Alex Wolszczan and Dale Frail announced they had discovered the first two exoplanets, or planets outside our solar system, while working at the Arecibo Observatory in Puerto Rico. The two planets orbit a pulsar, a neutron star, 2,300 light-years away, in the constellation Virgo. We now know of the existence of nearly 6,000 exoplanets, but Poltergeist and Phobetor were the first to be confirmed.

If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away? Researchers used a theoretical, modeling-based method, and this study is the first to analyze multiple types of technosignatures together rather than separately. The findings revealed that radio signals, such as planetary radar emissions from the former Arecibo Observatory, are Earth's most detectable technosignatures, potentially visible from up to 12,000 light-years away. Join Simon Steel, Deputy Director of the Carl Sagan Center, for a chat with lead author Sofia Sheikh about the research's findings and their implications for the search for technosignatures.

Three phenomenal women in space share their stories with us this weekend, in honour of Asteroid Day — a UN-recognised initiative raising awareness about the potential impacts, and opportunities, of these marvels of astronomy. Asteroid Day takes place on 30 June, the anniversary of the Tunguska event in 1908 where a meteor destroyed a landmass of about 2,150 km2 (a little smaller than the landmass of Luxembourg) of forest in Siberia, Russia. Asteroid Day was co-founded in 2014 by physicist Stephen Hawking, B612 Foundation president Danica Remy, astronaut Rusty Schweickart, film-maker Grigorij Richters and astrophysicist (and Queen guitarist) Brian May. Now recognised by the UN, Asteroid Day is celebrated globally to raise awareness about asteroids and their potential impact on Earth. It also raises awareness of the potential to mine asteroids as we move towards a space economy. My guests this week are: - Julie Payette - a Canadian engineer, scientist and astronaut who also served as Governor General of Canada from 2017 to 2021 - Wanda Díaz-Merced - astronomer using using sonification - Hoor Abdelraman Al Maazmi - space science researcher at the UAE Space Agency - Maher Kalaji - Board Director of the Asteroid Foundation and founder of the newly to be announced Luxembourg Rocket Society. Julie Payette joined the Canadian Space Agency (CSA) in 1992 as a member of the Canadian Astronaut Corps. She completed two spaceflights, logging more than 25 days in space. Dr. Payette also served as capsule communicator (CapCom) at NASA Mission Control Center in Houston and from 2000 to 2007 as CSA's chief astronaut. Julie was named COO for the Montreal Science Centre in July 2013. In 2017, Prime Minister Justin Trudeau announced that Queen Elizabeth II had approved the appointment of Payette as the next governor general of Canada which she started that October until January 2021. Wanda Díaz-Merced was born in Puerto Rico and lost her eyesight gradually through her teenage years into early adulthood. She talks about this experience and her long journey to become an astronomer who uses sonification to turn large data sets into audible sound. Currently, Wanda works at the European Gravitational Observatory Cascina, Italy, where she is the Director of the Arecibo Observatory. Dr Díaz-Merced received an internship with Robert Candey, an incredible mentor to her, at the NASA Goddard Space Flight Center in Maryland, USA, and went on to complete a Ph.D. in computer science at the University of Glasgow. Wanda was then accepted as a post-doctoral fellow at the Center for Astrophysics | Harvard & Smithsonian, and South African Astronomical Observatory in Cape Town. Wanda's work has also included collaborations with the European Gravitational Observatory proposal REINFORCE and the National Astronomical Observatory Japan (NAOJ).  Dr Díaz-Merced creates sonification software to perceive space in a different sensory way. Hoor Abdelraman AlMaazmi is a space science researcher at the UAE Space Agency and a member of the Emirates Mars Mission science team since 2017. The Mars mission, named ‘Amal' or ‘Hope,' launched in 2020. The UAE is going to send a spaceship to explore the solar system's main asteroid belt due to launch in 2028. For this mission, they will look at six asteroids with the target to land on the seventh- Justitia. This asteroid is thought to be one of only two known red asteroids and potentially laden with organic substances. The aim for this MBR Explorer is to deploy a landing craft to study the surface of Justitia fully developed by private UAE start-up companies. https://asteroidfoundation.org/ https://royalsociety.org/about-us/who-we-are/diversity-inclusion/case-studies/scientists-with-disabilities/wanda-diaz-merced/ https://space.gov.ae/en/initiatives-and-projects/uae-mission-to-asteroid-belt-ema https://www.instagram.com/uaespaceagency?igsh=ZXgwcnR3dTNqOHFs https://x.com/uaespaceagency?s=21

In this episode:00:49 The search for animals' magnetic sense sufferers a potential setbackExactly how animals sense Earth's magnetic field has long eluded researchers. To understand it, many have turned to the fly model Drosophila melanogaster, long thought to be able to detect magnetic fields. However, a recent Nature paper has raised questions about this ability, a finding that could have repercussions for scientists' efforts to understand the mechanism behind magnetic sensing, one of the biggest questions in sensory biology.Research article: Bassetto et al.News & Views: Replication study casts doubt on magnetic sensing in flies10:53 Research HighlightsThe world's first filter feeder, and human-caused climate change in the Bronze Age.Research Highlight: This ancient reptile wanted to be a whaleResearch Highlight: Bronze Age deforestation changed Europe's climate13:03 An iconic observatory shuts downThis week the famed Arecibo Observatory in Puerto Rico shut down.

In 2020, a devastating cable break led to the end of one of the most iconic radio telescopes in the world. It starred in movies, kept us safe from asteroids, and listened for extra-terrestrial life. The science done at Arecibo Observatory was (and continues to be incredibly important), and having the observatory in Puerto Rico is a point of pride for locals. We take a look at the history, science, and social importance of Arecibo, and talk about what the observatory's next chapter may look like. Thanks to our guests on this episode: Dr. Edgard G. Rivera-Valentín, planetary scientist Dr. Christopher Salter, retired radio astronomer Dr. Tapasi Ghosh, retired radio astronomer Pia Salter-Ghosh, “child of the observatory” Olga Figeroa Miranda, current director of Arecibo Observatory AeroEspacial is a four-part series from AirSpace that presents stories of Latino history, culture, and people at the heart of aviation and space.

“Take heart, daughter; your faith has made you well” (Mt. 9). Genesis 12:1-9                                    Psalm 33:1-12 Rome 4:13-25 Matthew 9:9-13, 18-26 1. What is faith? This may be the most important question of our time. This week the indictment of our former president reminds us how questions of trust underlie every human relationship and institution. [i] In 1996 Mary Doria Russell published a science fiction novel called The Sparrow. It imagines a near future in 2019 when the Search for Extraterrestrial Intelligence (SETI) program at the Arecibo Observatory discovers sung music coming from near Alpha Centauri. Jesuit priests led by the linguistics scholar Father Emilio Sandoz organize a mission to that world. They travel to Rakhat via newly invented technologies developed from mining asteroids. With the turn of a page it is suddenly the year 2060. Sandoz seems to be the only survivor and returns to earth. Damaged physically, psychologically and spiritually he tries to answer his superior's accusations. The reader experiences the story in parallel in two temporal settings both as Sandoz and his friends encounter a whole new form of human-like life, and much later as he explains what went wrong. It is an anthropological pleasure to imagine the language and society of the inhabitants of Rakhat. One almost wants to stop reading there before the inevitable disaster. Emilio Sandoz grew up surrounded by drug crime in Puerto Rico and first began to be educated by the Jesuits as a teenager. He has always struggled with doubt. As the story unfolds he begins to see the circumstances that brought the team together as more than a coincidence. As he finds his place among the far more social, even herdlike, inhabitants of Rakhat they physically touch him and he discovers a new conviction about God, a kind of ecstasy that fulfills him. This makes his disappointment so much worse when through his actions everything falls apart and he causes the death of his old friends and new ones. Near the end of the story two priests talk about Sandoz's struggle with faith. The Father General says, “There's an old Jewish story that says in the beginning God was everywhere and everything, a totality. But to make creation God had to remove Himself from some part of the universe, so something besides Himself could exist. So he breathed in, and in the places where God withdrew, there creation exists.” “'So God just leaves?' John asked, angry where Emilio had been desolate. ‘Abandons creation?' ‘No. He watches. He rejoices. He weeps. He observes the moral drama of human life and gives meaning to it by caring passionately about us, and remembering.' ‘Matthew 10:29… “Not one sparrow can fall to the ground without your Father knowing it.' ‘But the sparrow still falls.'” [ii] These are two different pictures of faith. First, as a kind of disposition which is a grateful response to good things in our life. This attitude is nonetheless vulnerable to suffering that leaves us wondering whether the good outbalances the pain. Or second, faith can be regarded as the knowledge of a silent watcher, a loving but invisible companion who is with us, but constrained in the help that can be provided. 2. If someone asked us to describe our faith we might say something like that. But today Matthew offers a very different and surprising kind of answer to the question “what is faith.” My friend Matt Boulton likes to describe the Christian year as divided in half. There are six months of holidays from Advent through Epiphany, Lent and Easter. Then six months of ordinary time which begins now. He says this rhythm is like inhaling and exhaling or like the tide coming in and going out again. Ordinary, does not mean commonplace, it means ordinal as in part of a series. In this case it means a series of episodes from the Bible that teach us how to live and give us a framework for interpreting our experience. [iii] The first eight chapters of the Gospel of Matthew describe Jesus' birth, his later baptism, temptation in the wilderness, the calling of his followers (the fisherman on the sea of Galilee), then his first sermon and stories of healing. In chapter nine Jesus invites the one who seems to be the last of the twelve disciples, a tax collector named Matthew. Imagine Matthew's daily life charging taxes on goods going to market. The author of the gospel uses the word tax collector as a synonym for sinner. People hate tax collectors for three reasons. First, taxes were cripplingly high. Second, these taxes were levied by, and to pay, an occupying army that punished and crucified the local people. Tax collectors are collaborators in this oppression. Finally, tax collectors extorted more money than required and did this for the sake of enriching themselves. Jesus immediately befriends and shares a meal with Matthew and “many tax collectors and sinners” (Mt. 9). I wonder what the other disciples thought about this. The pharisees, a group seeking to purify the religion of the time, deride Jesus for the company he keeps. Jesus does not make the argument that these people are not really sinners. Instead he says that like a physician he has come not to heal the healthy but the sick. The first readers of this story would know about the purity rules in the books of Leviticus and Numbers in the Old Testament. It says that menstruating women were regarded as unclean and corpses were too. Anyone and anything, including furniture like beds or chairs, that a bleeding woman touched would also become unclean. [iv] Jesus in the very act of responding to criticisms of the sinners attracted to him, is interrupted by a leader of the synagogue. This man kneels before him and begs for him to heal his daughter saying, “lay your hand on her, and she will live” (Mt. 9). As Jesus  goes with all of his disciples following him a woman touches his clothes. It's amazing that there are words spoken in the Bible that we still use today. Haimorreow is our word for hemorrhage and means to bleed. For twelve years this woman has been bleeding. For twelve years she has been unclean, isolated and literally untouchable. We hear a little of her internal dialogue. She says to herself, “If only I touch his cloak, I will be made well” (Mt. 9). The word for “made well” is sōzō related to the word sōtēr for savior. It does not just mean to be physically healed. It means to save, preserve, heal or rescue. Imagine the drama of this situation. An unclean woman goes through a crowd surrounding a great and holy teacher without permission, past his disciples, through the law that forbids it, and in effect desecrates him. The disciples must have been stunned and wondered what Jesus would say. Jesus does not rebuke her or criticize her actions. He loves her. He commends her boldness. Not only that but rather than taking credit for his healing power, he emphasizes her role in this miraculous healing. He says, “Take heart daughter, your faith has made you well” (Mt. 9). When Jesus arrives at the synagogue leader's house everyone knows that touching a dead body makes you unclean. But Jesus takes her by the hand and she gets up. The tax collector, the hemorrhaging woman and the synagogue leader come from entirely different stations of life but they teach us that faith is boldness. It is the conviction that our more daring efforts will be met by a loving God. During Pride Month it is especially important to linger for a moment here. We also need to recognize the way that Jesus interprets scripture. Jesus is not a prisoner to a simplistic and literalist reading of ancient texts. Jesus uses one text, “I desire mercy not sacrifice” (Hosea 6:6) to interpret other texts, for instance those having to do with sinners, menstruating women and corpses. In our time we need to be more diligent in reading the Bible in ways that nurture and love LGBTQ+ and all people. So for Matthew faith means more than just gratitude for the goodness of our existence. It refers to more than just a silent but compassionate watcher in our lives. Faith is a boldness in trusting God even when we cannot perfectly understand what is happening to us. The theologian Karl Barth (1886-1968) writes, “This is Abraham's faith: Faith which, in hope against hope, steps out beyond human capacity across the chasm which separates God and man, beyond the visibility of the seen and the invisibility of the unseen, beyond subjective and objective possibility… to the place where he is supported only by the Word of God.” [v] This week I received a letter from a dear friend who has been going through four terrible family tragedies this year. During the last of these tragedies he describes time moving so slowly, that his mind became his own worst enemy. He writes about being unable to pray, about screaming a bad word at the top of his lungs when he was home or in the car alone. He says that because he has faith in God, Jesus, the church he kept coming to this place, even though it brought up a tidal wave of feeling and grief. But then he heard a setting of “Ave Maria” sung by a visiting choir. He began stopping by “Our Lady of Flowers” the photographic image of Mary, and for instant had a kind of vision in which Mary held his family member on her lap. Then in a sermon he was reminded about a dream that the Medieval mystic Julian of Norwich had. In it she held a hazelnut in her hand which represented everything God had created. She worried about its destruction. But God reassured her saying that he would draw all things to himself. My friend concluded saying, “Mary seems to be my path back to mending my relationship with God.” What is faith? This may be the most important question of our time. May there always be the faith of gratitude for our existence. May we begin to experience God as the quiet, compassionate witness to our life. But above all, my dear ones, let us be audacious and bold in the places where we are supported only by the Word of God. In the beginning God was everywhere and everything. Lay your hand on us and we will live. Take heart daughter your faith has made you well.

In 1974, astronomers used the Arecibo Observatory to send a message to a star cluster called M13. It is located 25,000 light years away. So if anyone is there, their response will get to us in 50,000 years!! So then what was really the point of sending that message? Plus what language do you use to communicate with aliens? Please join astrophysicist Salman Hameed in exploring these questions and more.For the video of this podcast: https://youtu.be/4bTrmQTAywM

Plasma lensing near the eclipses of the Black Widow pulsar B1957+20 by Fang Xi Lin et al. on Thursday 24 November Recently, several eclipsing millisecond pulsars have been shown to experience strong and apparent weak lensing from the outflow of their ionized companions. Lensing can be a powerful probe of the ionized plasma, with the strongest lenses potentially resolving emission regions of pulsars. Understanding lensing in the `laboratory-like' conditions of an eclipsing pulsar may be analogously applied to fast radio bursts, many of which reside in dense, magnetized environments. We examined variable dispersion measure (DM), absorption, scattering, and flux density in the original Black Widow pulsar PSR B1957+20 through an eclipse at the Arecibo Observatory at 327 MHz. We discovered clear evidence of the two regimes of lensing, strong and apparent weak. We show that the flux density variations in the apparently weak lensing regime can be modeled directly from variations of DM, using geometric optics. The mean effective velocities in the ingress, $954pm 99$ km/s, and egress $604pm 47$ km/s cannot be explained by orbital motions alone, but are consistent with significant outflow velocity of material from the companion. We also show that geometric optics can predict when and where the lensing regime-change between weak and strong occurs, and argue that the apparent weak lensing is due to averaging many images. Our framework can be applied in any source with variable electron columns, measuring their relative velocities and distances. In other eclipsing pulsars, this provides a unique opportunity to measure companion outflow velocity, predict regions of weak and strong lensing, and in principle independently constrain orbital inclinations. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2208.13868v3

Vi har været til rumkonference på DTU den 24. marts, hvor der både blev annonceret store nyheder, talt om Danmarks deltagelse i den europæiske rumorganisation ESA og vist eksempler på aktuelle, danske rumaktiviteter. Hvis man har fulgt bare en lille smule med, så ved man nok at det blev annonceret at Andreas Mogensen skal på ny mission til Den Internationale Rumstation – og vi fangede Andreas til en kort kommentar. Vi fik også en snak med ESAs generaldirektør Josef Aschbacher om Danmarks forhold til ESA og betydningen af Andreas' nye mission. Derudover har vi samlet en stor håndfuld rumnyheder og bonushistorier, altsammen lige her i RumSnak. God fornøjelse

What a special episode for all of you today! Around The Reel welcomes filmmaker Andrew Hernández & composer Ben Thatcher to our show! Andrew has a new documentary out entitled "The Biggest Dream". The Arecibo Observatory fell in 2020. This radar system was vital for so many reasons, not just for planetary defense but for the citizens in Puerto Rico. We dive into the project, the reasons Andrew felt it was necessary to tell this tale, the challenges making it, what its like creating a feature length documentary and how the collaboration with Ben was accomplished! Orchestra and all! This is truly an inspirational, fun and informative conversation not only for filmmakers but everyone on the planet! We all have so much going on in our lives and have no idea how important things are outside of our day to day! Take a listen and enjoy our conversation with Mr. Andrew Hernández and Mr. Ben "Super Hero Composer" Thatcher! Enjoy!Buzzsprout - Let's get your podcast launched!

Explore the dynamics and engineering of Tethered Asteroid systems to adjust the orbital trajectory of near-Earth object (NEO) and potentially hazardous asteroids (PHA) with our guest Flaviane Venditti, PhD who is pioneering the tethered asteroid R&D. Topics in this month's Podcast Episode include tether dynamics, engineering, and materials (i.e. carbon nanotubes), alternative orbital deviation methods, tether anchoring, solar sails, and tethered balloon asteroids Podcast Guest: Flaviane Venditti, PhD, Observatory Scientist, Head of Planetary Radar, The Arecibo Observatory at University of Central Florida Dr. Venditti started her scientific career as a Bachelor in Physics/Astronomy at the University of Sao Paulo, where she was part of the Polarimetry group working with observations at the National Laboratory for Astrophysics (LNA) in Minas Gerais, Brazil. Besides observations, she was also interested in celestial mechanics and space missions, which led her to pursue a Master's (2009) and Ph.D (2013) degree in Space Engineering at the National Institute for Space Research, Brazil, focused on Astrodynamics. During her Ph.D, she worked with orbital maneuvers around irregularly shaped bodies, developing a method to model the gravitational field of asteroids with low computational effort using Arecibo's planetary radar data.

We are gonna take a look at the WOW signal! What is it? Where did it come from? Is Owen Wilson involved? Well hopefully we'll find out… Maybe not… Who knows!   Some of you have heard of the wow signal and you may know a little about it already, hopefully we can give you guys some more insight today.    The story starts back in 1959 when two Cornell university physicists, Philip Morrison who was a professor of physics at the Massachusetts Institute of Technology (MIT). He is known for his work on the Manhattan Project during World War II, and for his later work in quantum physics, nuclear physics and high energy astrophysics and Giuseppe Cocconi, who was an Italian physicist who was director of the Proton Synchrotron at CERN in Geneva. He is known for his work in particle physics and for his involvement with SETI. These two nerds speculated that there might be a specific radio frequency that an intelligent extraterrestrial life would use if they were trying to make contact. That frequency is 1420 megahertz.   https://youtu.be/M-SKyGnpTpM   That frequency was chosen for a particular reason, it is the same frequency naturally emitted by hydrogen. Now if you're up on your elements you know hydrogen is the most common element in the universe. It stands to reason, therefore, that hydrogen and thus its frequency would be familiar to any intelligent civilizations in the universe.    Then between 1965 and 1971 The Ohio State University Radio Observatory carried out the Ohio Sky Survey. Data was collected using the Big Ear radio telescope. The observatory was a Kraus-type (after its inventor John D. Kraus) radio telescope.  The observatory was part of The Ohio State University's Search for Extraterrestrial Intelligence (SETI) project. Construction of the Big Ear began in 1956 and was completed in 1961, and it was finally turned on for the first time in 1963. The survey was primarily at a radio frequency of 1415 MHz, but data was also collected and evaluated at 2650 MHz and 612 MHz. Only one "channel" or band of frequencies was sampled for each frequency. The antenna was oriented to one declination at a time, (a declination is the angular distance of a point north or south of the celestial equator) and as the sky drifted past the meridian field of view, radio energy from that area was received and detected. Signal power was plotted on an analog chart recorder and also digitized and recorded on magnetic tape for later processing. A given declination was observed for a number of days before the telescope was moved to another declination in a systematic fashion.   The area surveyed was from declinations 63 degrees north to 36 degrees south, with a resolution at 1415 MHz of roughly 40 arc minutes in declination by 10 arc minutes in right ascension (RA). Over the course of the Survey, 19,620 sources at 1415 MHz were identified, of which 60% were previously uncataloged.   Some of the objects first identified by the Ohio Survey included quasars, objects of intense radiation and power at the edge of the then-known universe. The archived data subsequently permitted these and other sources to be reviewed over several years of observations. Later, the LOBES survey used most of the same apparatus as the Ohio Survey, and was able to automatically determine and verify the sources first charted by the Ohio Survey.   After the Ohio Sky Survey, Big Ear was put to use for Ohio State's SETI  research program. The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets. Now we are already getting kind of nerdy so we are not going to get into the history of SETI and all of the people that were involved throughout the years. It would basically be its own big nerdy episode. It's pretty awesome and interesting to get into if you've got the time to get into it. Actually, it sounds like an awesome Patreon Bonus. But for now the basic description is all you need… People looking for intelligent life throughout the universe. Because, well, there isn’t a whole lot here on earth. The Ohio State seti program lasted from 1973-1995 and made the 1995 Guinness book of world records for the longest running seti program. It was during this 22 year run that the WOW signal came into being. So with that history out of the way let's get to the signal itself… There's going to be some sciencey stuff so get ready to get your nerd on!     On August 15, 1977 as Big Ear was scanning the heavens, it received a remarkable signal. Astronomer Jerry R. Ehman was sifting through data for several days and came across the signal. On a piece of printed tape with mostly 1s 2s and 3s there was the occasional higher number and then he noticed a line that contained the following sequence, 6EQUJ5. Ehman circled the section in red and wrote a little note in the margin... one word… that word? It was “poop.” No one knows why he wrote “poop” next to the sequence, either. And of course that’s stupid and I made it up. No, you silly fuckers! The word was, of course… “WOW!” The signal seemingly came from the direction of the constellation Sagittarius and contained the expected hallmarks of extraterrestrial origin! Aliens, bitches!!   The sequence string 6EQUJ5, commonly misinterpreted as a message encoded in the radio signal, represents in fact the signal's intensity variation over time, expressed in the particular measuring system adopted for the experiment. Got that? Good.  The signal itself appeared to be an unmodulated continuous wave, although any modulation with a period of less than 10 seconds or longer than 72 seconds would not have been detectable. So basically the letters and numbers  represent how strong or intense the signal was as compared to the constant background noise. If the signal was longer than 72 seconds any modulation in the signal would not have been able to be detected.    Ok so the intensity of the signals were measured at a signal to noise ratio. Basically they would constantly measure the noise coming through to determine a baseline reading to compare any received signals to. The signal was sampled for 10 seconds and then processed by the computer, which took 2 seconds. Therefore, every 12 seconds the result for each frequency channel was output on the printout as a single character, representing the 10-second average intensity, minus the baseline. So essentially every 12 seconds a series of numbers were printed out giving the researchers an idea of how strong any signal that might be received was as compared to the baseline noise.    The numbers and letters were part of an alphanumeric system set up by the researchers to determine signal strength. If there was just a blank space that meant the signal was between 0-1. This means a signal between the baseline and one standard deviation above the baseline. So essentially there's no signal but the baseline noise coming back. This is why when you look at the printout there are mostly spaces and 1s as there was no signal side from baseline noise coming back. The numbers 1 to 9 denote the correspondingly numbered intensities (from 1 to 9); intensities of 10 and above are indicated by a letter: "A" corresponds to intensities between 10 and 11, "B" to 11 to 12, and so on. So we know that was a bit tedious but that information is needed to understand just why the series of numbers and letters was so incredible. The wow signal had the highest intensity measured at the value of U. This means that while most of the returns were between 0-2 deviations above the baseline the WOW signal hit U which means it was around 30-31 deviations above the baseline! So in layman's terms imagine you're watching your tv at a volume level of 1 and all of a sudden it hits a volume of 30 that's kind of what we're dealing with. And if you're wondering, the frequency that the WOW signal was detected at was indeed around the 1420 that we mentioned earlier. The frequency that was suggested as the most likely for use by an intelligent civilization trying to make contact.    The length of the signal does not necessarily mean that the 72 seconds was the total length of the signal though. The Big Ear radio telescope was only adjustable for altitude (or height above the horizon), and relied on the rotation of the Earth to scan across the sky. Given this fact, sure to the speed of the Earth's rotation, any signal could only last a max of 72 seconds until the rotation of the earth took the radio telescope out of the way of the signal. The signal strength would be shown to get gradually louder then gradually softer as the telescope approached and then went away from the source of the signal. This is what we see with the WOW signal.    Though the signal came from the general direction of the Sagittarius constellation, due to the telescope's design it was not possible to pinpoint the location exactly. The Big Ear telescope, which featured two feed horns, each receiving a beam from slightly different directions, while following Earth's rotation. The Wow! signal was detected in one beam but not in the other, and the data was processed in such a way that it is impossible to determine which of the two horns received the signal. The region of the sky in question lies northwest of the globular cluster M55, in the constellation Sagittarius, roughly 2.5 degrees south of the fifth-magnitude star group Chi Sagittarii, and about 3.5 degrees south of the plane of the ecliptic. The closest easily visible star is Tau Sagittarii. If you know what all that means… More power trip you… if not, were with you! No nearby sun-like stars were within the antenna coordinates, although in any direction the antenna pattern would encompass about six distant stars.    So now after all that… What the fuck was the signal? Where exactly did it come from? Was it aliens?   Many different hypotheses have been put forth over the years although none have really gained traction with scientists and astronomers due to the strangeness of the situation.   One hypothesis that was presented early on was that the signal was actually a signal generated from earth and reflected off of some space junk and picked up by the telescope.  Ehman has said: "We should have seen it again when we looked for it 50 times. Something suggests it was an Earth-sourced signal that simply got reflected off a piece of space debris." Ehman backed off of this suggestion after further research showed an Earth-borne signal to be very unlikely, given the requirements of a space-borne reflector being bound to certain unrealistic requirements to sufficiently explain the signal. Also, it is problematic to propose that the 1420 MHz signal originated from Earth since this is within a protected spectrum: a bandwidth reserved for astronomical purposes in which terrestrial transmitters are forbidden to transmit.    The reason Ehman suggested this theory is that they searched for the signal again many times and were never able to find it again. This lead to a few other hypotheses like the signal was a rotating signal similar to a lighthouse beacon or that it was just a one time signal shot in our direction like maybe something knew we were scanning!  In a 2012 podcast, scientific skeptic author Brian Dunning concluded that a radio transmission from deep space in the direction of Sagittarius, as opposed to a near-Earth origin, remains the best technical explanation for the emission, although there is no evidence to conclude that an alien intelligence was the source.   Speaking of looking for it again, there have been many attempts to locate the signal since it was found. As stated Ehman and his crew searched for it many times to no avail.    Robert H. Gray looked for the signal in 1987 and again in 1989. Gray is a data analyst, astronomer, and author. He wrote the book The Elusive Wow: Searching for Extraterrestrial Intelligence. Gray heard about the WOW signal a few years after it had been discovered and contacted Ehman. He went and visited Big Ear, and spoke with Ehman, Robert S. Dixon (director of the SETI project) and John D. Kraus (the telescope's designer). In 1980 gray set up a commercial telecommunications dish in his Chicago backyard and started scanning the skies for some trace of the wow signal. He began to run and monitor his small SETI Observatory regularly in 1983 but still could not find a trace of the wow signal. In 1987 and 1989 he led searches for the wow signal using the Harvard/Smithsonian META radio telescope at the Oak Ridge Observatory in Harvard, Massachusetts. In 1995 and 1996 Gray would again search for the signal. This time he would pair up with Kevin B. Marvel and use the Very Large Array radio telescope in New Mexico. Kevin B. Marvel has served as the Executive Officer for the American Astronomical Society, the largest professional organization for researchers in astronomy and related disciplines, since July of 2006.  He began work with the AAS as Associate Executive Officer for Public Policy in 1998 establishing the Society’s public policy program becoming Deputy Executive Officer in 2003.  Before taking up a position with the American Astronomical Society in 1998 he served as a postdoctoral fellow at the California Institute of Technology's (CALTECH’s) Owens Valley Radio Observatory. He received his Ph.D. in Astronomy in 1996 from New Mexico State University.  So you know… This guy knows his shit.  The Very Large Array, or VLA for short, is a centimeter-wavelength radio astronomy observatory located in central New Mexico. Astronomers using the VLA have made key observations of black holes and protoplanetary disks around young stars, discovered magnetic filaments and traced complex gas motions at the Milky Way's center, probed the Universe's cosmological parameters, and provided new knowledge about the physical mechanisms that produce radio emission. Gray became the first amateur astronomer to use the VLA, and the first individual to use it to search for extraterrestrial signals. In 1998, he and University of Tasmania professor Simon Ellingsen conducted searches using the 26-meter dish at the Mount Pleasant Radio Observatory in Hobart, Tasmania. Gray and Ellingsen made six 14-hour observations where the Big Ear was pointing when it found the Wow! signal, searching for intermittent and possibly periodic signals, rather than a constant signal. No signals resembling the Wow! were detected. In 2011, Gray published the book The Elusive Wow: Searching for Extraterrestrial Intelligence, summarizing what is known about the Wow! signal, covering his own search for the signal, and offering an overview of the search for extraterrestrial intelligence. In 2016, Gray published an article in Scientific American about the Fermi paradox, which claims that if extraterrestrials existed, we would see signs of them on Earth, because they would certainly colonize the galaxy by interstellar travel. Gray argues that the Fermi paradox, named after Nobel Prize-winning physicist Enrico Fermi, does not accurately represent Fermi's views. Gray states that Fermi questioned the feasibility of interstellar travel, but did not say definitively whether or not he thought extraterrestrials exist. This guy is like the king of searching for the wow signal. He, more than anyone else, had kept the dream alive so to speak of finding this signal again.    In 2017 a new theory emerged that got people talking. The headlines all over science publications read that the mystery had been solved. Everyone dove into this theory. Antonio Paris, of St Petersburg College, thought discovered the explanation: a pair of comets. The work was published in the Journal of the Washington Academy of Sciences.   These comets, known as  266P/Christensen and 335P/Gibbs, have clouds of hydrogen gas millions of kilometres in diameter surrounding them.   The Wow! Signal was detected at 1420MHz, which is the radio frequency hydrogen naturally emits.   Notably, the team had verified that the comets were within the vicinity at the time, and they report that the radio signals from 266/P Christensen matched those from the Wow! signal. They used three of world's biggest radio telescopes: the Parkes radio telescope in Australia (210 feet or 64 metres in diameter), the National Radio Astronomy Observatory in West Virginia (140 feet or 40 metres in diameter), and Arecibo Observatory in Puerto Rico (the world's largest at 1,000 feet or 300 metres in diameter). In his paper, Paris wrote that comets will, under certain conditions, emit radio waves from the gases that surround them as they zoom closer to the sun. According to the study, Comet 266P/Christensen was in about the right position on the right day in 1977.    Several astronomers, including Ehman, think Paris is wrong about the comet. Ehman looked at Paris' study with Robert Dixon, who directs the radio observatory at The Ohio State University (Big Ear was destroyed in 1997). Two big issues are that the signal didn't repeat, and it appeared for such a short time. Ehman noted that the Big Ear telescope had two "feed horns," each of which provides a slightly different field of view for a radio telescope.    "We should have seen the source come through twice in about 3 minutes: one response lasting 72 seconds and a second response for 72 seconds following within about a minute and a half," Ehman told Live Science. "We didn't see the second one."   The only way that can happen, he said, is if the signal was cut off abruptly. A comet wouldn't produce that kind of signal, because the gases that surround them cover large, diffuse areas. Nor would the comet have escaped from the radio telescope's field of view that fast.          The other issue is the frequency of transmission. Paris said he has shown that comets can emit in that range, but Seth Shostak, a senior astronomer at the SETI Institute, is skeptical. Shostak used to study emissions from neutral hydrogen in the 1,420-MHz range, and is less sure the emission would look right. Comets may not generate enough hydrogen to make a bright enough signal like Wow!.     "I don't think anyone ever found such emission from comets," Shostak told Live Science.   In late 2020 another theory came about.  A star! First, some background. Back in 2013, the European Space Agency launched the Gaia space observatory to map the night sky — to determine the position, the distance, and the motion of stars with unprecedented accuracy. So far, Gaia has mapped some 1.3 billion stars, allowing astronomers to begin creating the most detailed 3D map ever made of our galaxy. The mission is expected to continue until 2024. Gaia’s new star map has significantly improved our understanding of the galaxy and the stars within it and this gave amateur astronomer Alberto Caballero an idea. The Gaia database is now significantly more detailed than the star catalog that John Kraus studied in the 1970s. Perhaps the new database might reveal the source of the Wow! signal, he reasoned. So Caballero repeated the search, looking for Sun-like stars among the thousands that have been identified by Gaia in this region of the sky. By Sun-like, he means stars that share the same temperature, radius and luminosity .   The search returned just one candidate. “The only potential Sun-like star in all the WOW! Signal region appears to be 2MASS 19281982-2640123,” says Caballero. This star sits in the constellation of Sagittarius at a distance of 1800 light-years. It is an identical twin to our Sun, with the same temperature, radius, and luminosity.   Of course, Caballero’s work does not mean that 2MASS 19281982-2640123 must have been the source. He points out that there are many stars in that region of the sky that are too dim to be included in the catalog. One of these could be the source. And there are some 66 other stars in the catalog that Caballero identified as potential candidates but with less strong evidence. These match the Sun’s temperature but data about their luminosity and radius is currently incomplete. So future data releases from Gaia and other mapping projects might yet reveal them as matches. For the moment, 2MASS 19281982-2640123 is our best bet and a good candidate for future study. Caballero says an obvious goal would be to look for signs of exoplanets orbiting this star. It could also be prioritized for study in the radio part of the spectrum.    So what else could it be? Could it still be an alien signal coming from a distant planet?  Ehman isn't convinced it's aliens, either. There are many phenomena that show sudden appearances and disappearances of radio signals, including fast radio bursts (FRBs), which are mysterious radio bursts with hotly-debated astrophysical origins that generate irregular signals that last only milliseconds. Fast radio bursts are intense bursts of radio emission that have durations of milliseconds and exhibit the characteristic dispersion sweep of radio pulsars. The first was discovered in 2007 by Lorimer, although it was actually observed some six years earlier, in archival data from a pulsar survey of the Magellanic clouds. It was dubbed the “Lorimer Burst”. Many FRBs have since been recorded, including several that have been detected to repeat in seemingly irregular ways. Most FRBs are extragalactic, but the first Milky Way FRB was detected by the CHIME radio telescope in April 2020. When the FRBs are polarized, it indicates that they are emitted from a source contained within an extremely powerful magnetic field. The exact origin and cause of the FRBs is still the subject of investigation; proposals for their origin range from a rapidly rotating neutron star and a black hole, to extraterrestrial intelligence. If the Big Ear picked up only the tail end of such an emission, the data could look similar to the Wow! signal, Ehman speculated.   "The issue with the feed horns is something no one can explain, including me," Paris said. "There is some data out there to suggest the issue is at the telescope end and not the phenomenon itself." So it's possible that the signal could have been caused by a glitch in the Big Ear telescope.   Was that E.T. or was it not E.T.? Nobody knows,” Seth Shostak, senior astronomer at the SETI Institute, tells Astronomy. “Nobody has ever found another explanation for what that might have been. It's like you hear chains rattling in your attic and you think ‘My god ghosts are real.’ But then you never hear them again, so what do you think?” Most importantly, Shostak says that if the signal wouldn’t have had Wow! written across it, no one would’ve ever heard of it. One-off signals like this were common back in the early days of SETI, when observatory computers were too primitive to notify astronomers of discoveries in real time, or perform rapid-fire follow-ups.    Despite uncertainties on signals picked up from across space, scientists continue to look for signs of alien life. For instance, NASA's TESS mission hopes to find exoplanets. The effort has already led to the discovery of “hot Saturn” planet TOI 197.01. Lead author Lisa Kaltenegger, a professor of astronomy in the College of Arts and Sciences and director of Cornell’s Carl Sagan Institute, said that life might exist in different types of worlds, but what we know is that there is a world like ours who can support life. Thus, it makes sense to search for Earth-like planets.   So all this being said we found a race of aliens originating from the constellation of Sagittarius. These guys could have been the ones that sent the signal. You wanna know about them… Well we gonna tell you about them either way.    Bellatricians are one of many races stated by people to be an actual, existing species of extraterrestrial life. As such, they appear in alien conspiracy theories, most notably those expressed by Sheldan Nidle and his life partner, Colleen Marshall.    Bellatricians are stated as being a bipedal dinosaurian/reptilian hybrid with scaly, multicolored skin that seems to possess a sort of luminosity. These scales are similar in design to those of a crocodile and can be green, yellow, brown, or even red in coloration. With this in mind, green and yellow are the dominant scale colors. Overall, they are very scaly and bony. A large bony crest surrounds their upper head, while a small bony crest runs up the middle of the back and connects to the larger crest found on top of the head.   Their eyes are large and protruding, and can be either red or dull yellow in hue, resembling those of Earth's reptiles. They are set forward on the face just above and to either side of their very small nose. These eyes have been stated (by Colleen Marshall) as "conveying more warmth than I had ever thought possible".   Their mouth has thin lips that run from one side of the head to the other, presumably filled with razor-sharp teeth. Ears are tympanic in nature, like a frog's; the only sign of their existence is a circular patch of extra-smooth, 3 inch (7.62 centimeter) diameter area on either side of the head just behind the eyes.   Thin hands are attached to their arms, and are armed with six long, clawed fingers. The feet have five toes which end in small yet very sharp claws. While they do possess a tail, it is short, only extending to the feet, although it is thick like that of a crocodilian. They exhibit sexual dimorphism, with males being slightly shorter than females.   This reptilian creatures are notable for their great skills in leadership and diplomacy. They speak in a very coarse and guttural tone, their speech filled with deep growling and hissing noises. They require between 5 to 8 hours of sleep daily.   The Bellatricians migrated from the constellation of Sagittarius around 25 million years ago into the area surrounding the constellation of Orion. They are now found some 112.5 light years from Earth. For the past 6 million years, they were in charge of all the former Alliance forces for our sector of the Milky Way Galaxy. However they were finally accepted into the Galactic Federation far more recently, approximately 3 years ago.   Former members of the League of Orion, it is stated that the Bellatricians presented themselves as tyrannical overlords in the Milky Way galaxy for eons. During this time, they were the oppressive ruling class for the Draconian Empire. However, now they are attempting a transformation, and aspire to be accepted as trustworthy members of the galaxy. They are now a very curious and benevolent group that wish to connect with Earth and exchange perspectives on our shared history. They are also open to connecting with those who wish to have an experience during dreamtime. It is proposed that the more open and accepting that humanity can be, the more likely we are to attract an "otherworldly" experience.   The Bellatricians have expressed their sincere desire to make amends for the atrocities they have performed throughout the ages. They are trying their hardest to let go of their natural self-serving attitude and are learning to embrace the joy received when in service to others. They wish to have a gentle introduction to those who can open their hearts, and forgive them for what they represented in the past, and instead accept who they are today. They are very solemn and serious beings, and thereby do not grasp the concept of humor, especially that which is derived from the misfortune of others.    So what about their technology?   Here's what we know: Scout Craft: Look like dew drops and beetle, and can vary in length from 100-400 ft (30.5-122 meters). Mothership: Look like large tadpoles, and very enormously in length, from 1-400 miles (1.6-640 kilometers) across.   Could they be the source of the signal? Jon believes they are!   There we go passengers! A little bit more light-hearted and nerdy episode for you guys. With all of the alien talk around these days we figured this would be a fun episode to speculate upon! What do you guys think?

Exploring the legacy and the future of the Arecibo telescope in Puerto Rico

Science Senior Correspondent Daniel Clery regales host Sarah Crespi with tales about the most important work to come from 57 years of research at the now-defunct Arecibo Observatory and plans for the future of the site. Sarah also talks with Toman Barsbai, an associate professor in the school of economics at the University of Bristol, about the influence of ecology on human behavior—can we figure out how many of our behaviors are related to the different environments where we live? Barsbai and colleagues took on this question by comparing behaviors around finding food, reproduction, and social hierarchy in three groups of animals living in the same places: foraging humans, nonhuman mammals, and birds.

If you are a regular ADU listener, you must be aware of all the latest industry rumors pertaining to this new DJI drone. Now, you shall be enthused to learn that DJI's has submitted their FCC filings for this new drone, the remote controller, and the FPV goggles. Does this latest development indicate that DJI is gearing up for a Christmas release? Tune in to this segment of the show for a sneak peek. Our next story is about police drones. Specifically, the Sacremento police and the Chula Vista polcie have been using drones, albeit in different ways. The Sacremento police is sending out FPV drones to document site conditions AFTER the law enforcement officers have assumed charge. Whereas, the Chula Vista police is using the DJI Matrice 300 and the Skydio as first responders. What do you think about drones being used for police work?

It's been more than a month since an asteroid-hunting telescope in Puerto Rico has gone dark. The Arecibo Observatory's dish is broken after a piece of scaffolding fell, damaging the surface. So what will it take to fix it?

Films like Armageddon and Deep Impact paint a catastrophic picture of asteroid strikes on Earth, and they can be cataclysmic. Ask the dinosaurs. That's why scientists like Alessandra Springmann of University of Arizona's Lunar & Planetary Laboratory keep eyes on the skies to monitor near-Earth passages of asteroids and other celestial debris. Springmann is the guest speaker at this month's First Friday Astronomy Event at Boise State's Science and Education Building and she joins Idaho Matters to talk about tracking space rocks from the Arecibo Observatory in Puerto Rico.

Here is the news.The world&`&s largest radio telescope has been put into use in a mountainous region of southwest China&`&s Guizhou Province.The Five-hundred-meter Aperture Spherical Telescope, or FAST, is built to explore space and hunt for extraterrestrial life. Chinese President Xi Jinping sent a congratulatory letter to scientists, engineers and builders on the launch.Located in a karst valley, construction of the project started in 2011, 17 years after it was proposed by Chinese astronomers. The whole project cost 1.2-billion-yuan, roughly 180 million U.S. dollars.The installation of the telescope&`&s main structure was finished in early July. It was a 4,500-panel reflector as large as 30 football pitches.In a recent trial observation, the telescope received a set of high-quality electromagnetic waves from a pulsar around 1,300 light-years away.Nobel laureate Joseph Taylor at Princeton University in the United States said the telescope will certainly generate enthusiasm, bring people into science, and make China important in the world of science.The astronomer was awarded the Nobel Prize in physics in 1993 for discovering indirect proof of gravitational waves with the assistance of Puerto Rico&`&s Arecibo Observatory. The observatory is home to a radio telescope that is 350 meters in diameter.This is Special English.The National Tourism Administration has released ratings, listing the best and worst scenic spots, tourism agencies, tour guides and tourists during the national holiday week in early October. The ratings are part of new efforts by the administration to strengthen supervision and management of the tourism market and to improve services offered by scenic spots and their staff. It also aims to create a favorable environment for travelers during holidays.In the ratings, some attractions, including the Palace Museum in Beijing, were praised for their management and smooth operations. Other places, including the Three Gorges Tourism Zone in Hubei Province were credited for their contribution to the national "tourism toilet revolution" campaign. This is an initiative sponsored by the administration to renovate public toilets at tourism spots nationwide. Almost 600 million trips were logged during the weeklong holiday which started on October 1. The administration said that thanks to effective measures taken by the tourism departments at all levels, there were no serious disputes or accidents during the holiday. Beijing Zoo received 450,000 tourists during the holiday. Four visitors were each fined 50 yuan, roughly 7 U.S. dollars and 50 cents, for feeding animals. It was the first time the zoo has issued tickets to tourists for this reason.You&`&re listening to Special English.

The Ukraine-built vessel was first put into use in 1994 and can break ice that is 1.2 meters thick.This is Special English.China will further tighten the land management of villa construction.The Ministry of Land and Resources said that compared with previous regulations released as early as 2003, the new rules will target terraced houses, semi-detached houses, and garden houses. The previous regulations suspended the land supply of detached villas only.Analysts say the measure is going to make villas scarce in the future. The adoption of the universal second-child policy in China has continued to drive the demand of villa sales, but villa owners are reluctant to sell their property.Data shows that the market price of villas in Guangzhou, the capital city of Guangdong province, has seen a more than 10 percent increase, especially in the outskirts of the city. However, villa sales in the city have seen a 20 percent drop in the first half of this year, compared to the same period last year. The Chinese authorities have urged the local governments across the country to make better use of construction land. Cities and towns should specify their land use objectives before the end of this year to ensure a 20 percent cut in construction land use per unit of GDP by 2020.

The world's largest radio telescope will be completed and in use in late September, accompanied by regulations to protect the facility. The construction of the Five-hundred-meter Aperture Spherical Telescope, or FAST, has entered its final phase in the mountainous southwestern province of Guizhou. With a dish the size of 30 football pitches, the telescope, which measures 500 meters in diameter, dwarfs Puerto Rico's 300-meter Arecibo Observatory. The provincial legislature passed a rule to guarantee the safe operation of the facility. The rule will come into effect later this month. Under the regulation, the telescope requires radio silence within a 10-kilometer radius. Construction of irrelevant projects will be prohibited in the core area and violators will be fined up to 100,000 yuan, roughly 15,000 U.S. dollars. The regulation also bans activities including hunting, wood gathering or land reclamation in the core area, and underscores forest fire prevention work. The rule sets Sept. 25 as the prefecture's astronomical science day. Construction of the telescope began in March 2011 at a cost of 1.2 billion yuan. Some 8,000 people in the core area will be relocated. This is Special English. China's top legal authorities have for the first time clearly stipulated that victims of miscarriages of justice have the right to compensation for mental anguish. The Supreme People's Court has revealed a judicial explanation saying that compensation applications can be filed in non-criminal cases where people have been wrongfully subjected to law enforcement. To redress judicial infringement, the court and its staff should eliminate ill effects, rehabilitate reputations and extend formal apologies to victims. For mishandled cases which result in serious harm, the judiciary should apologize and pay compensation for mental suffering. Those who have had their assets illegally frozen or sold off by the court can also ask for compensation. This is Special English. China is moving quickly to implement the anti-corruption consensus reached at the Group of 20 Summit by setting up the group's first anti-graft research center in Beijing. The center will provide intelligence support in the hunt for economic fugitives and confiscation of their ill-gotten assets. The center is based at Beijing Normal University and will officially begin operations in a few months. Dozens of experts and professionals who specialize in graft-related studies from China and other G20 economies will be recruited. The country's top discipline watchdog said the establishment of such a center will lay a solid foundation for studies of cross-border corruption crimes and offer intelligence support to fight corruption globally. The center will conduct in-depth research among G20 members on corruption crimes, including comparing domestic and foreign laws, procedures for confiscating illegal assets and extradition and judicial assistance. Transnational commercial bribery will also be studied. The center will also set up a database of experts and lawyers from G20 members with knowledge of anti-corruption law enforcement, criminal law and asset recovery. These experts will conduct research and training and will share their experiences in tackling such problems. You're listening to Special English. I'm Mark Griffiths in Beijing. Authorities and experts have warned of the risks of the Zika virus spreading in China and are urging precautionary measures, as the number of cases in Southeast Asia increases. Authorities responsible for entry and exit inspection and quarantine across China are urged to intensify monitoring and cooperation in the prevention and control of the virus. Visitors to countries and regions with a Zika outbreak should take precautionary measures, including wearing long-sleeve clothes and long trousers, and should see doctors quickly if they are bitten by mosquitoes and display symptoms such as fever and rash. Those who plan to return from such countries should make declarations to the exit-entry inspection and quarantine authorities. Southeast Asian countries including Singapore, Indonesia and Thailand, and many South American countries, have reported Zika cases. According to the World Health Organization, more than 2 billion people living in Asia, Africa and the Pacific could be at risk. The risks for China will depend on importation of the disease, the presence of a suitable host and the country's capacity to detect and respond to its spread. The Zika virus is primarily spread through mosquitoes, and around 20 percent of those infected could display symptoms including fever, rash or headache. Death may occur in rare cases.

A 144-hour visa-free entry policy, which allows greater flexibility for foreigners who go to Shanghai and nearby provinces, has boosted the number of inbound tourists in the Yangtze River Delta. The Shanghai General Station of Immigration Inspection said that as of Sept 1, more than 18,000 foreign tourists had taken advantage of the policy to enter Shanghai for a short stay. That's 60 percent more than in 2015. Since Jan 30, when China enacted the expanded visa-free policy, eligible visitors or businesspeople traveling in the Yangtze River Delta area, including Shanghai, Hangzhou and Nanjing, automatically qualify for 144 hours for business or simply to explore the region. Visitors from 51 countries can enjoy the policy, including the United States, the United Kingdom and Japan. In the past, Shanghai and other important mainland tourism destinations only offered a 72-hour visa-free stay for inbound foreign visitors. Travel industry insiders say the average stay of foreign visitors is around 102 hours. Industry insiders all attribute the growth to a rebound in inbound tourism in China. In the first half of this year, almost 68 million visits were paid by overseas visitors, a jump of 4 percent year-on-year. Visits by foreigners reached 13 million, a 9 percent increase.

The Shanghai Jewish Refugees Museum hopes that documents about Jewish refugees' life experience in Shanghai during World War II will eventually be listed in China's national legacy archives. The museum said it will continue enriching and improving its collection of historical materials and make the material part of the national legacy archives, and then global archives. It revealed the plan at the third Jewish Studies Youth Forum. At least 20,000 Jewish people sought shelter in Shanghai during the war, or used the city as a jumping-off point for other safe destinations. Documents related to Jewish refugees' lives in Shanghai during the 1930s and 1940s were listed in the municipality's legacy archives last year. The museum has registered 550 items documenting the Jewish experience so far, including tickets for the voyage from Europe to Shanghai, certificates for job applications, as well as audio and video recordings of interviews with former refugees. The Hongkou district was Shanghai's Jewish quarter in the 1940s, when a large number of Jewish refugees poured from Europe into the open harbor of Shanghai, which didn't require a visa for entrance. Shanghai had a Jewish community as early as the late 19th century. The Jews there engaged in various businesses including running cafés and photo studios. You're listening to Special English.

The material cools by not only taking away sweat like ordinary fabrics do but also by allowing the heat that the body emits as infrared radiation to pass through, which makes the wearers feel cooler than they would when wearing cotton clothes. The researchers' study was recently published in the journal Science. The lead author of the study, Yi Cui, is an associate professor of materials science and engineering at Stanford. He said by cooling the person rather than an entire building, a substantial impact could be made on global energy use. The human body emits mid-infrared radiation, an invisible and benign wavelength of light. That contributes to more than 50 percent of the total body-heat loss in a typical indoor setting like an office. However, traditional textiles are not designed for infrared radiation control.

The Bruce Lee Club in Hong Kong founded by fans of the legendary kung fu star has closed, after 15 years of operation due to rising rent in one of the world's most expensive property markets. This mini-museum and souvenir shop in Kowloon has action figures, toys, films and memorabilia related to the martial arts icon. It held an auction of its collection on Sept. 3 including a rare porcelain figure of Bruce Lee with an estimated market value of 100,000 Hong Kong dollars, roughly 13,000 U.S. dollars. Income from the auction will be used to cover expenses and for redundancy pay. The club said it aimed to bring members from around the world together to express and exchange their feelings towards Bruce Lee and to promote martial arts, philosophy and arts films. The shop had already cut its space by half to reduce costs, but was still unable to cover the rising rent. Chairman W Wong said the shop was in operation for 15 years, and it was more like a venue for fans to meet rather than a profit-making business. This is Special English. Preliminary competitions are going on for the first ever national contest of the traditional Chinese poker game "The Landlord", or Dou Di Zhu in mandarin. The competition, entitled "Two-Against-One Poker Championships" was co-sponsored by China's General Administration of Sport. The winner will be rewarded with five million yuan, and all players can cumulate their master points that will be the basis for a national ranking of Landlord poker players. Online registrations are open and free of charge. Preliminary matches will be held online and last until June next year. More than 2,000 players will be selected for the final competition. A deputy director from the administration said she is confident that the competition will become a popular event. The administration is expected to see a total of more than 100 million people enrolling online. The event came after the administration granted official status to the poker game in the "card and chess category" for the national games earlier this year. The authority also published a set of rules and regulations for the poker game and an assessment system for points and ranking. "The Landlord" normally consists of at least three players: one being the landlord and the other two, the uprising peasants. The peasants play in a team against the landlord. Any player who feels confident about his or her cards can claim to be the Landlord at the beginning and receive three extra cards. This is Special English. （全文见周六微信。）
