On March 3, 2024 my Catalina Sky Survey teammate Kacper Wierzchos was asteroid hunting with our 60 inch telescope on Mt. Lemmon, Arizona when he spotted a fuzzy object in the constellation of Draco.  After Kacper reported his discovery to the Minor Planet Center, observers in Arizona, New Mexico, and Tenerife confirmed it to be a comet and it was given the name C/2024 E1 (Wierzchos).  Kacper's discovery has a hyperbolic orbit indicating that after coming slightly closer to the Sun than the planet  Venus on January 21, 2026 it will be ejected from the solar system never to return.

I was observing with the Catalina Sky Survey 60 inch telescope on Mt Lemmon, Arizona when a fast moving object appeared on a set of four images of the same area of the night sky. After I sent the discovery observations to the Minor Planet Center this new object was observed by telescopes in Arizona, Germany , South Bohemia in the Czech Republic , Chile, Pennsylvania , Italy, Hungary, and France. 2017 FE101's unusual path about our Sun is inclined by 53 degrees to the plane where the planets and most of the rest of the asteroids are located. In September of 2016 it was not observed by humans as it streaked by at an amazing 22 miles per second. Once every 125,000 years or so a 5 football field sized asteroid like 2017 FE101 collides with our planet producing a crater 4 or 5 miles in diameter, inflicts damage over a hurricane sized foot print on the Earth's surface, and in some cases throws up enough debris into the atmosphere to produce global climate change. Since on its current path, 2017 FE101 can't come closer than about 21 times the moon's distance from us , this very large space rock is not currently classified as a potentially hazardous asteroid. Rest assured that my team the Catalina Sky Survey and asteroid hunters world wide will keep track of 2017 FE101 as it comes near to Mars and Earth to make sure that its path does not change to make it a threat to our home planet.

My Catalina Sky Survey teammate Greg Leonard was asteroid hunting in the constellation of Hydra with our Schmidt telescope on Mt. Bigelow, Arizona when a fast moving unknown point of light passed through a set of his images.After Greg reported his observations to the Minor Planet Center for the next 10 days it was tracked by observatories in Arizona, Italy, Hawaii, Australia, and Argentina.  Citizen scientist H. A. Güler analyzed these data.  The Minor Planet Center published the discovery of the near Earth asteroid 2018 CN41. The discovery was deleted when the object turned out to be a Falcon Heavy Rocket Upper stage with a Tesla roadster attached.

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - Jul 16, 2024. My Catalina Sky Survey teammate Carson Fuls discovered 2015 TC25 as a rapidly moving point of light in the night sky. Followup observations using data from four different telescopes has enabled a team of astronomers led by Dr. Vishnu Reddy of the University of Arizona's Lunar and Planetary Laboratory to determine that this small asteroid reflects four times more of the sunlight than do most other Earth approaching asteroids. Dr. Reddy points out that large asteroids are covered by a blanket of dust but that "Small asteroids might be bald and dust free." This team of researchers found the surface of Carson's discovery to be similar to a small meteorite which fell to Earth in France in 1836. - Jul 23, 2024. Dangerous Asteroids Are Still Out There! Recently my Catalina Sky Survey teammate Greg Leonard discovered a rapidly moving point of light in the night sky. Subsequent observations made by telescopes in Arizona, Romania, Illinois, the Czech Republic, Australia, and France revealed it to be a close approaching Potentially Hazardous Asteroid. The Minor Planet Center named it 2016 WJ1. This asteroid is about 200 yards in diameter, orbits the Sun once every 567 days, and currently can come to within about 26,000 miles of the Earth's surface. 2016 WJ1's orbit eventually will bring it near Mars, Earth, our Moon, and Venus. Any of these encounters have the potential to change it's path around the Sun.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - It was murky cloudy night on Mt. Lemmon where I was trying to find Earth approaching objects with the Catalina Sky Survey 60 inch telescope. At about 1AM another hole in the clouds opened and I could see stars on the all sky video camera. On this fourth attempt, one set of images showed a bright rapidly moving object. Followup observations by my teammate Greg Leonard using the Catalina Sky Survey 40 inch telescope next door and two different observers in Japan provided the data which allowed the Minor Planet Center to calculate an orbit, estimate a size, predict its path in the sky, and give it the name 2016 VA. Twenty hours after I discovered it, Dr. Gianluca Masi using the Virtual Telescope Project facility 56 miles south of Rome, Italy, repeatedly imaged 2016 VA as it made an 11 minute passage through the Earth's shadow. He used these images to make a remarkable video of this tiny asteroid as it passed through the Earth's umbra. It was the fastest asteroid that he had ever tracked. Fortunately a bit after this video, 2016 VA missed the Earth by about 59,000 miles while traveling at a speed of 13 miles per second relative to us. In 2024 it will once again come near to both the Earth and our Moon.   - Egg rock's chemical composition and visual appearance is so different from other native Mars rocks that scientists have concluded that it is a meteorite which came from the molten core of an ancient asteroid.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

My Catalina Sky Survey teammate Richard Kowalski was surprised to find a moving point of light on some his images which was more than 50 times brighter than a typical Earth approaching object he observes . He was even more amazed when it was not cataloged as a known object and he reported his observations to the Minor Planet Center. A couple of hours before Richard spotted it, scientists using the Space Surveillance Telescope in New Mexico had picked up this unknown object on some of their images but did not immediately report their observations. For the next 67 hours the new object was tracked by telescopes at 24 different observatories around the world. These observations allowed the Minor Planet Center to calculate an orbit, give it the name 2016 WM48, and classify it as a Centaur. Centaurs are named after the mythical beasts which were half human and half horse perhaps because they have characteristics of both asteroids and comets. Richard's object, 2016 WM48, is about a mile in diameter. We don't know if it has rings, tiny moons, or a gas cloud surrounding it as some other Centaurs do. 2016 WM48 must have had a catastrophic collision in the past few million years which put it on a very elliptical path which is tipped at 60 degrees or so to the solar system's plane. Centaurs do not have stable orbits. Their paths are changed as they come near to the giant planets Jupiter, Saturn, Uranus, and Neptune. A Centaur's fate is to likely collide with the Sun or a planet or perhaps even be ejected from the solar system

Recently my Catalina Sky Survey teammate Greg Leonard discovered, 2016 WJ1, a relatively large asteroid which can come close but will not hit the Earth. The extremely unlikely scenario of an impactor with our number on it would start the with the report of a fast moving point of light in the night sky. After a few days of data the Minor Planet Center would give it a name. Tracking the new asteroid, asteroid hunters would be alarmed as the chances that this object will impact the Earth starts to rise. Large telescopes would then be trained on it to obtain the pattern of colors in the light it reflects and use this information to determine its size, mass, and chemical composition. Hopefully this fictional impact would be far enough in the future so that humans could mount a space mission to intercept it and deflect it so that it would miss Earth. Even when a collision with this mythical object is certain, scientists would not be able to accurately predict its point of impact on the surface without additional tracking data. To be prepared civil defense organizations around the world would begin to think about the possibility of mass evacuations. Chances are that this would be a small object which would have a negligible effect on humanity. Much much much less likely is that this fictional impactor would be a once in every million years or so event which would cause global climate change disrupting human agriculture and plunge our society into a real crisis. The story you have just heard is a complete fantasy, however, there is a extremely tiny remote possibility that a real version of it could start tonight.

My Catalina Sky Survey teammate Jacqueline Fazekas was asteroid hunting with our small but mighty Schmidt telescope on Mt. Bigelow, Arizona when she spotted and then reported a bright moving point of light in the night sky to the Minor Planet Center.Given the rate of human caused climate change one has to wonder about the state of our planet in January of 2163 when 2024 ER is predicted to pass safely some 66 lunar distances from humanity.

My Catalina Sky Survey teammate Rose Matheny had no way of knowing that the fast moving point of light that she had just discovered would create such a stir.

Lemmon, Rose took over the world of asteroid hunting when she posted 82 new potentially Earth approaching objects on the Minor Planet Center's NEO Confirmation Page.

I denne episode af RumSnak tager vi turen fra Jorden og ud forbi Mars, Jupiter, Saturn, Uranus og Neptun, helt ud forbi Kuiperbæltet, dér hvor rummet for alvor er ved at blive mørkt og tomt. Men måske er der ikke helt tomt. Faktisk er der nogen der tror, at de har fundet en ny planet derude – Planet 9, som den kaldes indtil videre. Vi har besøg i studiet af Mike Alexandersen som er astronom på Minor Planets Center i Cambridge, Massachusetts, for at høre mere om Planet 9 – eller i hvert fald de observationer og simulationer som har givet anledning til hypotesen om bonusplaneten derude. Derudover skal vi selvfølgelig have et par aktuelle nyheder – og en held håndfuld bonusser – denne gang blandt andet om endnu en privat Månemission, om Euclid-missionen og om en dokumentarfilm med fokus på astronauters mentale og psykiske velbefindende.

Discovering asteroids in space used to be a privilege reserved for astronomers - until now, thanks to a project led by the University of Arizona Catalina Sky Survey, which made it possible for several members of the public to spot a previously unknown near-Earth asteroid on its orbit around the sun. 2023 TW closest found by citizen science Named 2023 TW, the newly discovered asteroid is the closest to ever be discovered by a citizen science initiative, according to Catalina Sky Survey researchers. Initial calculations indicate it ventures into Earth's vicinity at a "mean orbital intercept distance" of 375,000 miles, about 35,000 miles past the average distance between the Earth and the moon. "The mean orbital intercept distance describes how close an object approaches Earth's orbit," said Carson Fuls, director of the Catalina Sky Survey, which is based in the UArizona Lunar and Planetary Laboratory. "Earth might not be anywhere near the asteroid when it approaches a spot in its orbit." Despite its close proximity to Earth, 2023 TW does not pose a threat. There is no chance of 2023 TW impacting Earth, and even if this asteroid did enter our atmosphere, severe consequences would be unlikely, Fuls said. Spanning 164 feet, 2023 TW's diameter is similar in size to the meteor that created the 0.8-mile-wide Barringer Crater, also known as Meteor Crater, a popular sightseeing stop along Interstate 40 east of Flagstaff, Arizona. This is well below the threshold of 459 feet for potentially hazardous asteroids, according to Fuls. "For an object to be considered a potentially hazardous asteroid, both the distance and size need to be taken into account," Fuls says. "This asteroid meets the distance requirement, but not the size requirement." The project's public-facing portal, dubbed the Daily Minor Planet, began operating in June and allows volunteers to pore over images collected with a telescope on Mount Lemmon. Each night, the telescope surveys about 200 patches of the sky. A software algorithm flags anything that appears like it might be an object that is moving relative to the fixed stars in the background. A typical night of observing yields hundreds of such candidate detections. This is where the volunteer observers come in. Their task: decide which detections are actual asteroids and which ones are artifacts or other phenomena unrelated to asteroids. Aside from discovering 2023 TW, the project has reached the milestone of reporting 1,200 newly discovered, individual objects to the Minor Planet Center of the International Astronomical Union - the clearinghouse that decides whether objects detected anywhere in the solar system are real. Most of the objects reported through the project have been asteroids, but it also picked up the occasional comet. Comets are different from asteroids in that they contain water and other ices and typically reside in the outer reaches of the solar system. Before 2023 TW was found, the project's volunteers detected many other candidates for near-Earth asteroids. However, the timing is tricky: Many asteroids, particularly those close to Earth, whip around our planet quickly before heading out into space for another trip around the sun. To establish and publish an asteroid as a new discovery, asteroid trackers need to understand the object's orbit, which requires repeated observations over several days. "Close approaching asteroids appear so briefly in our sky and are moving so quickly that any delay in processing or reviewing the data increases the chance that they cannot be re-observed and confirmed," Fuls said. "Very close approaching asteroids may zip right past the Earth and quickly become too faint due to distance or go into the daytime sky where we can no longer see them." In other words: Time is of the essence. The recent asteroid discovery was made only two days after the initial observation. Beyond the time pressure, knowing how to tell real objects and false detections apart is a central co...

Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - Tonight, even though the chances are extremely slim, an asteroid hunter could find a sizable asteroid on a collision course with planet Earth. If we have decades warning, the potential impactor's arrival time could be changed by impacting the dangerous object with a high velocity mass or if we have less time we will need to nuke it which will either blow it to bits or give it a rocket like push. - To give you an idea of the asteroid traffic in our neighborhood, on a mostly cloudy night, through holes in the clouds, in a space of less than 2 hours, my Catalina Sky Survey teammate Richard Kowalski posted 7 new close approaching asteroid discoveries on the Minor Planet Center's Near Earth Object Confirmation Page.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Dr. Peter Veres talks about asteroids, comets, and meteors. He describes how the Minor Planet Center keeps track of observations and orbits. This data is publicly available, and non-scientists make valuable contributions. He also tells us about the AMOS meteor network, and how meteors connect to asteroids and comets. 

To give you an idea of the celestial traffic in our neighborhood, on a recent clear night, using our 60 inch telescope on Mt. Lemmon, Arizona, my Catalina Sky Survey teammate Hannes Groller posted 20 new objects on the Minor Planet Center's Near Earth Object Confirmation Page. In the future five of these asteroids may become a valuable source of raw materials for Martian colonists.

Thirty six hours before my Catalina Sky Survey teammate Rik Hill discovered it, a space rock about size of a Toyota Prius passed about 14,000 miles above the Earth's surface. When Rik first spotted it this small asteroid was about a million miles from us and was moving away from the Earth at 12.6 miles per second. Its orbit had been changed by a narrow escape from the Earth's gravity and it was on a new path around the Sun This small space rock was subsequently observed by telescopes in Russia and Arizona. The Minor Planet Center used these observations to calculate an orbit and give it the name 2015 SK7.2015 SK7 survived it's 2015 encounter with planet Earth. It may not be so lucky the next time.

Catalina Sky Survey teammate Richard Kowalski found a faint moving point of light in the night sky.  After his discovery observations were posted on the Minor Planet Center's website it was observed by 10 other telescopes around the world and given the name 2013 US10.  It has taken additional observations to reveal that Kowalski's object is not an asteroid but rather a comet which came closest to the Sun on November 15, 2015. After that its speed will be so great that it will leave our solar system never to return. Its path is not in the direction of any known star making it likely that it will continue its cold lonely journey till the end of time.

To give you an idea of the asteroid traffic in our neighborhood, on a mostly cloudy night, through holes in the clouds, in a space of less than 2 hours, my Catalina Sky Survey teammate Richard Kowalski posted 7 new close approaching asteroid discoveries on the Minor Planet Center's Near Earth Object Confirmation Page.

Ospite della serata Maura Tombelli, astrofila e cacciatrice di asteroidi. Di professione bancaria ma con una passione sfrenata per l'astronomia, detiene un vero e proprio record: il Minor Planet Center le attribuisce la scoperta di ben 197 asteroidi, in condivisione con altri astronomi. È al primo posto in Italia per numero di asteroidi scoperti e al primo posto al mondo tra le donne astronome non professioniste. Insieme a lei ci addentreremo per carpire i segreti di un'attività così prolifica e di successo internazionale. In diretta su Border Radio, dalle 21 alle 22

The one thousand six hundred and second potentially hazardous asteroid was discovered by the Pan-STARRS group in Hawaii. Followup observations were made by  telescopes in Hawaii, France, Australia, Italy, Germany, and Pennsylvania. The Minor Planet Center used these vital observations to calculate an orbit and gave it the name 2015 OC22.

Recently I was observing with the NASA funded Catalina Sky Survey 60 inch telescope on Mt. Lemmon when the computer identified a faint fast moving object in the night sky. Not being sure it was real I scheduled followup observations. About an hour later the second set of observations showed that it is a real object. On the next two nights this small space rock was observed by telescopes near Westfield, Illinois and on Kitt Peak in Arizona. These observations allowed the Minor Planet Center to determine an orbit and a tentative size. It was given the name 2015 GB.

A team of astronomers, including associate professor Chad Trujillo of Northern Arizona University's Department of Astronomy and Planetary Science, have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object observed in our solar system. The planetoid, which has been nicknamed “Farfarout,” was first detected in 2018, and the team has now collected enough observations to pin down its orbit. The Minor Planet Center has now given it the official designation of 2018 A-G-37. Farfarout's nickname distinguished it from the previous record-holder “Farout,” found by the same team of astronomers... For the written story, read here >> https://www.signalsaz.com/articles/nau-astronomer-on-team-confirming-orbit-of-most-distant-object-ever-observed-in-our-solar-system/

I was observing with the NASA funded, Catalina Sky Survey, 60 inch telescope on Mt. Lemmon, when I found an interesting moving point of light in the night sky. It appeared to be on the path of an Earth approaching asteroid. I submitted my observations to the Minor Planet Center. Telescopes in Germany, New Mexico, Illinois, Pennsylvania, and England observed it. The Minor Planet Center used these data to calculate an orbit. This orbit revealed the asteroid to be large enough and close enough to classify it as a Potentially Hazardous Asteroid. It was given the name 2015 BY310. A few days later the Minor Planet Center connected the observations of the object that they had been calling 2015 BY310 with an asteroid 2000 BK19. It had been discovered 15 years previously by the Lincoln Near-Earth Asteroid Research Program in New Mexico. These new data confirm that it is is an Earth approaching asteroid but that it is slightly smaller than is required to give it the potentially hazardous label.

I was observing with the Catalina Sky Survey, NASA funded, University of Arizona, 60 inch telescope on Mt. Lemmon when a bright fast moving point of light caught my attention. It seemed much too bright not to be known, but when I checked with the Minor Planet Center, it was not in any of their catalogues. It was was subsequently observed by more than a dozen telescopes scattered around the world and given the name 2014 YE42. The asteroid hunting community will be keeping track of 2014 YE42,in the extremely unlikely event that its path is changed, to make it a threat, as it passes other objects in space.

Astronomers find 20 new moons around Saturn and you can help name them Link: https://www.cnn.com/2019/10/07/world/saturn-20-new-moons-scn/index.html The discovery of 20 previously unknown moons around Saturn has helped the ring planet surpass all others in our solar system, according to the International Astronomical Union's Minor Planet Center. It now has 82 known moons; Jupiter has 79. The moons are all similar in size, spanning about three miles across. But 17 of the 20 have a retrograde orbit of Saturn, meaning they essentially orbit backwards from the planet and other moons. Carnegie Institute of Science astronomer Scott Sheppard and his team used the Subaru telescope in Hawaii to find the moons. Last year, Sheppard and his team located 12 new moons around Jupiter, including one with a retrograde orbit. "Studying the orbits of these moons can reveal their origins, as well as information about the conditions surrounding Saturn at the time of its formation," Sheppard said. Wanna name one of Saturn's moons? Scientists were able to locate the new moons thanks to more robust computing power and better algorithms for tracking faint distant objects, Sheppard said. What's more, you -- yes, you -- can help name the new moons. The contest opens Monday and will close on December 6. "I was so thrilled with the amount of public engagement over the Jupiter moon-naming contest that we've decided to do another one to name these newly discovered Saturnian moons," Sheppard said. "This time, the moons must be named after giants from Norse, Gallic or Inuit mythology."

Astrophiz 90: Sophia Nasr – Self Interacting Dark Matter and Galaxy Clusters This episode’s featured guest is Sophia Nasr, who is a fabulous graduate physics student at University of California, Irvine who is working on her PhD in cosmology and astroparticle theory with a focus on researching Self-Interacting Dark Matter. She brilliantly explains all forms of dark matter research and her passion for cosmology, equity, diversity and outreach. In the sky: Observation notes for September include Saturn, Jupiter, the Moon and Uranus. For those who enjoy watching Live Rocket launches on the internet put September 25 at 1357GMT into your calendar to watch a Soyuz rocket at the Baikonur Cosmodrome in Kazakhstan launch to take the crewed Soyuz MS-15 spacecraft to the International Space Station with members of the next Expedition crew. The capsule will remain at the station for about six months, providing an escape pod for the residents. For citizen scientists there is a nice opportunity to participate in the Globe at Night dark sky project, which is concerned with light pollution. For those in the Northern hemisphere you’ll be asked to report on what you can observe in the constellation Cygnus between Sept 20 and 29 and for Southern Hemisphere citizen scientists you be asked to report on what you can observe in the constellation Sagittarius on the same date range. To contribute to this worthwhile project, Northern observers can go to tinyurl.comFORWARDSLASHdarkskynorth And Southern observers can go to tinyurl.comFORWARDSLASHdarkskysouth And they are both all lowercase, all one word. In the News. First up it looks like we have an amazing new interstellar visitor, Congratulations to Gennady Borisov, for his discovery of comet C/2019 Q4 (Borisov). The first interstellar comet ever found and a truly skybreaking discovery! The Minor Planet Center has published the official announcement. Reports have also just come in today that water has been detected on a distant exoplanet. The reporting on this discovery is all over the Internet and all over the place in terms of accuracy. No, it’s not an earth-like planet. It doesn’t have water ‘on’ it because it’s most likely a Neptune-like planet with no actual surface, and you wouldn’t survive long enough if you were there to develop any habits. it’s becoming clearer and clearer that terms like ‘habitable’ and ‘goldilocks zone’ aren’t really effective tools for accurately communicating science to the public audiences. If you want to get the lowdown on habitability and exoplanets, you couldn’t do better than to follow Prof Jonti Horner and Dr Elizabeth Tasker on Twitter, or hear from them directly by checking out their episodes at AstrophizDOTcom It was also sad to hear that ISROs moon landing has run into problems but our fingers are crossed for them and other news from the moon is that the Chinese Rover has detected some strange gel-like substance in a crater. Next from the Xinhua news agency in China a discovery that may help unravel the long standing mystery of FRBs Chinese astronomers have detected over 100 repeated fast radio bursts (FRB) – These particular FRBs are mysterious signals believed to be from a source about 3 billion light years from Earth

During a recent 6 night observing run with the NASA funded Catalina Sky Survey 60 inch telescope on Mt. Lemmon, I found 29 Earth Approaching Asteroid candidates which were posted on the Minor Planet Center website. The largest of this collection of space rocks is 2014 JO25. It orbits the Sun every 3 years and is about 1/2 mile in diameter. Its closet approach to Earth is about 4.4 times the distance to our Moon at which time it is traveling in excess of 20 miles/second. We will continue to observe it, to make sure that it does not become an Earth impactor, as it passes near other objects in space.

My guest today is J.L. Galache, an asteroid astronomer turned new-space entrepreneur. J.L. is Co-Founder and Chief Technology Officer at Aten Engineering, a pioneering space mining company. He has designed and directed asteroid data projects with NASA’s Frontier Development Lab and Oracle. At the Minor Planet Center (part of the Harvard-Smithsonian Center for Astrophysics), J.L. was Acting Deputy Director, where he helped keep the world safe from killer asteroids.   We discuss space mining and the practical steps necessary for human settlement of the solar system — as well as what a space economy among interplanetary settlements would look like.   More on J.L. & Aten Engineering J.L. on Twitter: https://twitter.com/jlgalache Aten Engineering: https://www.atenengineering.com Aten on Twitter: https://twitter.com/AtenEngineering __________   More at: https://www.MindAndMachine.io

To give you an idea of the celestial traffic in our neighborhood, on a recent clear night, using our 60 inch telescope on Mt. Lemmon, Arizona, my Catalina Sky Survey teammate Hannes Groller posted 20 new objects on the Minor Planet Center's Near Earth Object Confirmation Page. In the future five of these asteroids may become a valuable source of raw materials for Martian colonists.

Dr. Matt Holman, head of the Minor Planet Center in Cambridge, Massachusetts, stops by to talk asteroids. The Minor Planet Center handles about a hundred thousand asteroid observations a night, from observatories all around the world. He talks about the difficulties in linking asteroid observations, and the discovery of the first interstellar asteroid, 'Oumuamua.

One of the Planetary Society’s 2018 Shoemaker Near-Earth Object grants has gone to astronomers searching the sky from a mountaintop in the North African nation of Morocco.  Observer Michel Ory tells us about their work.  Tim Spahr ran the Minor Planet Center for many years.  He has moved from that worldwide coordinator for asteroid and comet discoveries to NEO Sciences LLC, and served once again as chair of the Shoemaker NEO judging committee.  Wait till you hear what poor Yuri Gagarin had for lunch as he orbited Earth.  That’s just one thing you’ll learn from this week’s What’s Up segment.  Hear complete interviews and learn more at:   http://www.planetary.org/multimedia/planetary-radio/show/2018/0718-2018-spahr-ory-shoemaker-neo.htmlLearn more about your ad choices.

“Men's hearts shall fail from fear…for the planets of the heavens shall be shaken” (Luke 21:26). When rookie astronomer Irina Kirilenko discovers a planet-size comet in the Kuiper Belt on a collision course for Mars, she first faces stonewalling from the Minor Planet Center, then coercion and stricture from NASA. They press her to embrace an ingenious reinterpretation of her discovery and ban her from talking about it.  It slowly dawns on her that the government is fostering a massive conspiracy to keep the public oblivious to the truth—Earth is facing an existential threat. Unwilling to be silenced, she recruits fellow astronomer Ariele Serrafe to evaluate her discovery, placing both in the crosshairs of government agents. Set in a dystopian vision of the near future, The Rogue, the first volume of the Planets Shaken series, weaves the threads of biblical prophecy, ancient history, government conspiracy, and electric universe theory into a thought-provoking, tensely plotted thriller—one that asks us to reconsider the nature of the universe and the destiny of the world Join me for an exciting chat with Lee Brainard!

It will feature more than 300,000 entries, each with an average length of 1,000 words. It will be twice as large as the Encyclopedia Britannica. The online encyclopedia will cover more than 100 disciplines and be put into use in 2018.The project's editor-in-chief Yang Muzhi said China faces challenges from every corner of cyberspace, so it should have its own online encyclopedia to lead public opinion."According to Yang, the new encyclopedia's top rival is Wikipedia. The goal of the project is to surpass Wikipedia rather than play catch-up with it.Yang said people think Wikipedia is correct and authoritative, while it claims to be a free encyclopedia that anyone can edit. He said the idea is alluring, but China has the world's largest group of authors, so they can do better.This is Special English.The Palace Museum in Beijing plans to stop selling paper tickets from its box office, probably by later this year. An official from the museum says an Internet-based system will be set up to better coordinate the number of visitors for different hours of the day.He said the new plan is preliminarily scheduled to be launched in an "appropriate time in late October", but it still depends on whether conditions are ripe. Starting in July, the museum will gradually decrease the percentage of tickets available at traditional box offices.The Palace Museum opened its online ticket system in 2011. Almost half the tickets are sold via the internet. The tickets sold at the box office in the first quarter of this year decreased by 10 percent from the same period a year earlier.The Palace Museum, or the Forbidden City, was China's former royal palace from 1420 to 1911. It is one of the most visited museums in the world.

To say that my guest for this episode of the podcast, Luca Bracali, is a travel photographer would be too limiting, for he is also an expert TV director and a true explorer, having been to the North Pole, amongst other truly remote locations.My interest in Luca's work and personality, and the reason why I invited him to be a guest on the show, was sparked mostly from his commitment to the preservation of the environment and the deep respect and love he has for the Earth, its nature, and its people.Luca Bracali has travelled to 138 countries, is the author of eight books and the winner of eight prizes in international photographic competitions. Since 2008 he is a member of APECS (Association of Polar Early Career Scientists) for his contributions about the environment published in the media. In 2009 he was the only reporter to reach the geographic North Pole on skis. In 2010 Bracali debuted in the world of fine-art photography and his pictures have been on display, as solo exhibitions, in museums and galleries in Rome, Sofia, Kiev, Odessa, Copenhagen, Akureyri, Montreal and New York. He directed 150 shows for the Italian TV network RAI 1 and was a guest on over 40 programs and daily news aired on RAI networks as an explorer and documentary filmmaker. The Minor Planet Center in Cambridge named after him the 198,616th asteroid discovered. Three of his latest reportages have been published on National Geographic.Besides environmental issues, we discussed the special challenges photographers have to face when shooting in extreme climates, what it takes to be a TV director, ancient art as inspiration, and other topics.
