Big birds with bitty brains are still kind of brightWe've learned a lot about the remarkable intelligence of birds like crows and parrots, but not much work has been done on large flightless birds. A new study that explored the problem-solving abilities of emus, ostriches and rheas suggests that some of these birdy behemoths have impressive cognition too. In a first-of-its-kind study, a team led by University of Bristol's Fay Clark trained the birds to use puzzles to get food, and they found that the rheas and emus were able to solve the puzzle easily, though the ostriches did not. The research was published in the journal Scientific Reports.Cows jump over the moon — maybe humans should tooResearchers have done a lot of work to try and understand how astronauts can best prepare for and compensate for the muscle and bone atrophy that they will experience after long periods in zero G. A new study, led by Marco Chiaberge at Johns Hopkins University, suggests that a workout that includes jumping might be beneficial. The researchers found that by training mice to repeatedly jump up from one level to another increased their knee cartilage thickness by 26 per cent. The research was published in the journal npj Microgravity.Mary had a little lamb – 11,000 years agoSheep are among the animals that humans domesticated first, in the middle east during the dawn of agriculture. A new genetic study of hundreds of ancient sheep remains, which date across 12 millennia, is shedding light on the intertwined history of sheep and humans. The work, led by geneticist Dan Bradley of Trinity College Dublin, tells the story of how the sheep's domestication not only gave us clothes but also milk and meat which fueled our spread around the world for thousands of years, and how humans molded sheep by selecting them for colour and wool. The research was published in the journal Science.A tiny great ape lived in Europe 12 million years agoThe tiniest member of the great ape family — the group that today includes the chimpanzees, orangutans, bonobos, gorillas, and us — has been identified from fossils found in Germany. Nearly 12 million years ago, the 10-kilogram animal would have shared its environment with another, larger great ape species, something researchers didn't think was possible. David Begun, a paleoanthropologist at the University of Toronto, said its two fossilized teeth and a single knee bone indicated that Buronius manfredschmidi had its own ecological niche high up in the trees. The study was published in the journal PLOS One. The recipe for finding life on other planetsIn the last two decades we've discovered literally thousands of planets orbiting nearby stars. And our technology has advanced to the point where we're on the cusp of being able to investigate whether there's life on those planets. We speak to astrophysicist Lisa Kaltenegger, the founder of Cornell University's Carl Sagan Institute, about her work trying to answer that question, and her book Alien Earths: Planet Hunting in the Cosmos.

Prof. Dr. Lisa Kaltenegger ist eine führende Expertin für die Modellierung bewohnbarer Welten. Sie entwickelt Methoden, um Leben im Kosmos aufzuspüren, und arbeitete mit NASA und ESA in Österreich, den Niederlanden, Harvard, Deutschland und Cornell. Zu ihren Auszeichnungen gehören der Heinz-Meier-Leibnitz-Preis, der Doppler-Preis und der Barry-Jones Inauguration Award.

Melvyn Bragg and guests discuss some of the great unanswered questions in science: how and where did life on Earth begin, what did it need to thrive and could it be found elsewhere? Charles Darwin speculated that we might look for the cradle of life here in 'some warm little pond'; more recently the focus moved to ocean depths, while new observations in outer space and in laboratories raise fresh questions about the potential for lifeforms to develop and thrive, or 'habitability' as it is termed. What was the chemistry needed for life to begin and is it different from the chemistry we have now? With that in mind, what signs of life should we be looking for in the universe to learn if we are alone?With Jayne Birkby Associate Professor of Exoplanetary Sciences at the University of Oxford and Tutorial Fellow in Physics at Brasenose CollegeSaidul Islam Assistant Professor of Chemistry at Kings College, LondonAnd Oliver Shorttle Professor of Natural Philosophy at the University of Cambridge and Fellow of Clare CollegeProducer: Simon TillotsonReading list: David Grinspoon, Venus Revealed: A New Look Below the Clouds of Our Mysterious Twin Planet (Basic Books, 1998)Lisa Kaltenegger, Alien Earths: Planet Hunting in the Cosmos (Allen Lane, 2024)Andrew H.

We have identified thousands of planets just in our neighborhood in the Milky Way, mostly from the way they impact their host stars. Basic calculations suggest that there are countless more across the galaxy, and that billions of them could potentially support life. But what kind of life they host, and how we would be able to detect the presence of those biological processes from Earth, remain big questions in the world of exoplanets and astrobiology. What technologies might lie ahead to help us answer the question of whether we are alone in the universe? Lisa Kaltenegger, an astrophysicist and astrobiologist at Cornell University, talks to Janna Levin about that search, the atmospheric fingerprints of life, and why an advanced alien civilization might decide not to talk to us.

Are we alone in the universe? Alien Earths author Lisa Kaltenegger joins us to discuss new discoveries in humanity's hunt for extraterrestrial life. What We Discuss with Lisa Kaltenegger: The universe contains billions of stars and galaxies, with an estimated one out of five stars having a planet that could be similar to Earth in terms of potential habitability. Scientists use various methods to detect exoplanets, including observing changes in starlight and analyzing the light spectrum of planets to detect signs of life-sustaining elements like oxygen and methane. The search for extraterrestrial life involves looking for planets in the "habitable zone" or "Goldilocks zone" around stars, where conditions might allow for liquid water on the surface. The observable universe is limited by the speed of light and the age of the universe (approximately 13.7 billion years), meaning we can only see as far as light has had time to travel since the Big Bang. Anyone can contribute to space exploration and scientific discovery by staying curious, learning about new discoveries, and supporting science education. Even simple actions like looking up at the night sky and wondering about our place in the universe can inspire a lifelong passion for science and exploration. And much more...

She's a pioneer in figuring out how we might tell if any of the trillions of planets out there in the galaxy might harbor life – and if so, what kind of life.

Are we alone in the universe? Brian Cox and Robin Ince venture to Glastonbury in the search for Alien Life and are joined in their galactic quest by comedian Russell Kane and astronomers Lisa Kaltenegger and Chris Lintott. They imagine the sorts of worlds that might best host alien life, how some of the biological and technological signatures of alien life might appear as well as how evolution might shape this life. They discuss some of the mysterious signatures that have appeared as well as how hard it is to really know what you're looking for and how objects like faulty microwaves have muddied the alien finding waters.Producer: Melanie Brown Exec Producer: Alexandra Feachem BBC Studios Audio production

Neil deGrasse Tyson and comedian Matt Kirshen learn about exoplanet discovery on the frontier, how higher oxygen gave us dinosaurs, and what type of life could be out there with astrophysicist and astrobiologist Lisa Kaltenegger. NOTE: StarTalk+ Patrons can listen to this entire episode commercial-free here: https://startalkmedia.com/show/distant-aliens-space-dinosaurs-with-lisa-kaltenegger/Thanks to our Patrons Steve Solomon, Jeff Johnson, Duncan Corps, Rodrigo VM, Richard Kashdan, Jenn Long, Jeremy Shimanek, Gary Gaskin, and Longbow81 for supporting us this week.

Are we alone? This question continues to tantalize and mystify scientists and the public alike, wondering if Earth contains not only the one known sample of life in the Universe but also the ONLY life in the Universe. In her new book, Alien Earths, astrophysicist Lisa Kaltenegger (founding director of Cornell University's Carl Sagan Institute) "demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere" to inform our search for life beyond Earth. Communications specialist Beth Johnson chatted with Dr. Kaltenegger about her research, her writing, and the ever-improving tools available in our quest for answers. (Recorded 13 June 2024.)

Finding alien life could be just around the corner. At least, that's if the James Webb Space Telescope and other techniques help us discover their extraterrestrial homes. In this episode, astrophysicist Lisa Kaltenegger and author of new book Alien Earths: Planet Hunting in the Cosmos talks us through the ways she and her team are looking for these planets and the kinds of life they might hold.

If (or maybe when) we find alien life in the universe, will it look like us? As telescopes become bigger, our ability to peer into the cosmos is only getting better. So the question may not be “will we find something?” but rather “what exactly should we be looking for?”Lisa Kalteneggar is an astrophysicist and founding director of Cornell University's Carl Sagan Institute. She even works out of Sagan's old office and shares the same optimism and enthusiasm he brought to the search for extraterrestrial life. Abby Beall speaks to her about her new book Alien Earths: Planet Hunting in the Cosmos, which takes readers on a cosmic adventure to faraway exoplanets with oceans of lava and multiple suns. Through the conversation Lisa explains how Earth's geological history can help inform our search for life, while acknowledging alien life may not look the same as us. She discusses the technology that has allowed us to enter a new epoch of exploration – and what technological advancements are needed to help advance our search for alien life. And she examines the alien worlds that feature in various science fiction worlds, like those in Star Wars and Avatar, and whether they could actually exist somewhere in the universe.To read about subjects like this and much more, visit newscientist.com.

For thousands of years, humans have wondered whether we're alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life? As founding director of Cornell University's Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview - planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality. With the James Webb Space Telescope and Dr. Kaltenegger's pioneering work, she shows that we live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide, Dr. Kaltenegger shows how we discover not merely new continents, like the explorers of old, but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we're not alone? Lisa Kaltenegger is the Director of the Carl Sagan Institute to Search for Life in the Cosmos at Cornell and Associate Professor in Astronomy. She is a pioneer and world-leading expert in modeling potential habitable worlds and their detectable spectral fingerprint. Kaltenegger serves on the National Science Foundation's Astronomy and Astrophysics Advisory Committee (AAAC), and on NASA senior review of operating missions. She is a Science Team Member of NASA's TESS Mission as well as the NIRISS instrument on James Webb Space Telescope. Kaltenegger was named one of America's Young Innovators by Smithsonian magazine, an Innovator to Watch by Time magazine. She appears in the IMAX 3D movie “The Search for Life in Space” and speaks frequently, including at Aspen Ideas Festival, TED Youth, World Science Festival and the Kavli Foundation lecture at the Adler Planetarium. Shermer and Kaltenegger discuss: Carl Sagan and his influence • Sagan's Dragon • ECREE Principle • how stars, planets and solar systems form • how exoplanets are discovered • Hubble Space Telescope, Kepler Space Telescope, James Webb Space Telescope • The Origin of Life • Fermi's Paradox: where is everybody (the Great Silence, the Great Filter) • biosignatures • technosignatures • Dyson spheres • Will aliens be biological or AI? • interstellar travel • Kardashev scale of civilizations • how to talk to aliens when we can't even talk to dolphins • Deities for Atheists, Skygods for Skeptics: aliens as gods and the search as religion • why alien worlds matter.

As founding director of Cornell University's Carl Sagan Institute and author of the new ALIEN EARTHS: Planet Hunting in the Cosmos, Lisa Kaltenegger is one of the world's most respected cosmologists. She believes that, with our revolutionary new cosmological technologies, we are likely to “discover” non-human life somewhere in the cosmos. What's particularly astonishing about these kinds of conversations is how they no longer astonish us. Fifty years ago, the idea of discovering non-human life somewhere in the Universe was science fiction; today, it's become the mainstream scientific assumption of leading cosmologists like Kaltenegger and the Harvard astrophysicist Avi Loeb. The issue is not if we'll find these life-forms, Kaltenegger and Loeb are saying, but when. Astonishing.

Could A Planet Like Arrakis From ‘Dune' Exist?“Dune: Part II” is one of the year's most highly anticipated films, and it picks up where the first film left off: with Paul Atreides escaping into the desert on the planet Arrakis. It's a scorching-hot world that's covered in dunes, and home to giant, deadly sandworms.Obviously “Dune” and its setting are fictional, but could there be a real planet that resembles Arrakis? And if so, could it sustain life?Ira talks with Dr. Mike Wong, astrobiologist and planetary scientist at the Carnegie Institution for Science, about what Arrakis' atmosphere is like, the search for life in the universe, and what sci-fi films get wrong—and right—about alien planets.Preparing Astronauts For The Loneliness Of A Mars MissionNASA is preparing to send humans to Mars. Although the launch date has been pushed back over the years, the agency says it wants to get there in the 2030s. And it has a lot on its to-do list. NASA needs to build new rockets, new habitable living spaces, new spacesuits, and new radiation shielding, just to name a few items.But what if the one of the biggest challenges of these missions is not the engineering, but the mental health of the astronauts? Can all of the crew members get along with each other and stay alive over the course of three years in tight quarters and unforgiving environments? How will they cope with being separated from their families and friends for so long? And what lessons can they learn from astronauts who've lived on the International Space Station—and from our collective experience of isolation during the pandemic?A new documentary, out March 8, explores all these questions and more. It's called "The Longest Goodbye," and it dives into NASA's Human Factors program, which includes a group of psychologists who are trying to figure out the best way to preserve astronauts' mental health on a long and demanding mission.SciFri producer and host of Universe Of Art, D. Peterschmidt, spoke to the film's director, Ido Mizrahy, and one of its featured astronauts, Dr. Cady Coleman, about how NASA is thinking about tackling loneliness in space and what we can learn from astronauts who've already lived on the space station.Should The Aliens In “65” Have Known About Earth's Dinos?Some science fiction movies, like “Alien,” are instant classics. A good sci-fi movie weaves together themes of science and technology with a gripping narrative structure to create a memorable story that leaves the viewer with something to think about. But some (many) sci-fi movies leave the viewer with one thought: “Huh?”The 2023 movie “65” is in some ways a reversal of “Alien.” Instead of humans coming to an alien world and getting attacked by aliens, in “65,” an alien that existed 65 million years ago crash lands on Earth and gets attacked by dinosaurs. Oh, and the alien is Adam Driver. What's not to get?Sometimes, calling in a real-life scientist is the best way to wrap your head around science fiction. Dr. Lisa Kaltenegger, an astrobiologist at Cornell University, says that if there were advanced extraterrestrials near Earth during the age of the dinosaurs, our planet's life should have been no mystery to them. That's because around 300 million years ago, Earth's atmosphere had abundant oxygen and methane, two of the building blocks of life. Kaltenegger's own research has shown how Earth's atmosphere during that period would have been visible through a telescope—and indicated an even stronger potential for life than Earth's atmosphere today. She also saw “65” on a plane.Based on Kaltenegger's research, should Adam Driver have seen those dinosaurs coming? In an interview with Digital Producer Emma Gometz, she shares how telescopes can spot exoplanet atmospheres, why Jurassic Earth's atmosphere was special, and a few of her thoughts on “65.”Transcripts for each segment will be available after the show airs on sciencefriday.com.

Die Antwort auf eine der größten Fragen der Menschheit gibt's in diesem Podcast. Unser heutiger Gast wurde in Kuchl bei Salzburg geboren, lebt aber mittlerweile in den Vereinigten Staaten. Sie ist Professorin an der Cornell University, NY, NASA-Mitglied, Direktorin des Carl Sagan Institute, Astronomin, Astrophysikerin und Mutter. Ach ja, und der Typ, der den Mars-Rover lenkt, sitzt nur zwei Türen weiter von ihr.Im Gespräch mit carpe diem-Host Holger Potye erklärt uns Astrophysikerin Lisa Kaltenegger, woher ihre Leidenschaft für den Weltraum kommt, warum wir viel mehr auf den kleinen blauen Punkt im All (unsere Erde) aufpassen müssen und wie man sich als Frau in einer immer noch männerdominierten Wissenschaftswelt durchsetzen kann.Das Schlüsselerlebnis dazu lieferte ein Vortrag bei einer ESA-Konferenz in Holland, bei der ihr damaliger Chef zu ihr sagte: „Lisa, wenn du jetzt Folien kopieren gehst, wirst du immer Sekretärin bleiben, egal was du machst.“ Das war ein Life- und Career-Changing-Moment für die österreichische Wissenschaftlerin.Neuauflage ihres Sachbuch-Hits Das Timing für diese Podcastfolge passt perfekt, denn vor kurzem wurde ihr Bestseller „Sind wir allein im Universum?“ im ecoWing-Verlag neu aufgelegt. Darin begibt sie sich äußerst unterhaltsam und anschaulich (die Texte werden durch Comic-Grafiken unterstützt, die einen spielerischen Zugang zu komplexen Themen schaffen) auf Spurensuche nach E.T., Wall-E und Co.Sherlock für die Schule Lisa tritt auch dafür ein, dass wir Schule und Lernen mehr als Detektivarbeit inszenieren sollten, wo man rauskriegen muss, was als Nächstes passiert. Die Challenge der Erziehung besteht darin, die Freude am Lernen und am Wissen zu vermittelnWas wir außerdem aus dieser Episode mitnehmen:• Metrodoros von Chios (ja, das ist einer dieser alten Griechen) hat wohl als Erster die Frage nach außerirdischem Leben gestellt.• Jeder Stern ist eine Sonne. • Potenziell könnte um jeden 5. Stern am Nachthimmel ein Planet kreisen, der wie unsere Erde sein könnte. Es gibt also 40 Milliarden möglicher Erden in unserer Galaxie.• Penny aus der TV-Serie „Big Bang Theory“ könnte sich niemals die Wohnung gegenüber von Leonard und Sheldon leisten, die beide auf die private Spitzenuniversität Caltech gehen.• Wenn man die Erde mit einem Apfel vergleicht, dann ist ihre Atmosphäre, die uns am Leben hält, dünner als die Schale des Apfels. • Die Fehlerkultur in den USA ist komplett anders. Wenn etwas nicht klappt, lautet die Anschlussfrage: Und, wie probierst du es als Nächstes? So gelingen Forschungsdurchbrüche. • Warum die Erde als Ausflugsziel für Aliens noch nicht interessant genug ist.• Warum das ELT (extremely large telescope) am Anfang 42 Meter Durchmesser haben sollte.Und wir lernen, wie hoch die Wahrscheinlichkeit ist, dass wir tatsächlich allein in unserer Galaxie sind.

If there was life on other planets, what might it look like, and would they even bother coming to Earth? 

In Folge 90 geben wir nicht auf und ergeben uns auch nicht! Wenn die Aliens kommen, sind wir bereit. Aber können sie uns überhaupt finden? Wir schauen uns an, ob und mit welchen Methoden und außerirdische Zivilisationen entdecken können. Da wurde tatsächlich wissenschaftlich geforscht, mit spannenden Ergebnissen. Außerdem: OSIRIS-REx geht nicht auf, der Mond ist alt und Planeten gehen kaputt (nicht bei uns). Evi hat den passenden Film zum Thema, nämlich “Galaxy Quest”. Bei Grabthar's Hammer!

In Folge 79 machen wir uns auf die Suche nach Magrathea. Im Sci-Fi-Klassiker “Per Anhalter durch die Galaxis” ist das der Planet auf dem eine Superzivilisation lebt, die Luxusplaneten bauen kann. In der Astronomie nennt man so Planeten, die ein Doppelsternsystem aus weißen Zwergen umkreisen. Ob es so etwas tatsächlich gibt, wissen wir nicht. Aber aktuelle Forschung zeigt, dass es solche Himmelskörper zumindest theoretisch geben kann. Wir reden außerdem noch über Wasserwolken auf Enceladus und Evi erklärt in einer neuen Folge von “Science Frames”, warum man sich den Film “Planet 51” ansehen sollte und wie es wäre, wenn wir Menschen einmal die Aliens wären.

Der Benecke widmet sich Hirnimplantaten. Und wir sprechen mit der Astrophysikerin Prof. Lisa Kaltenegger über die Suche nach außerirdischem Leben.

Lisa Kaltenegger is the founding director of the Carl Sagan Institute at Cornell. In 2009, Kaltenegger realized that a telescope like JWST would see only tiny signals from atmospheric gases during each transit, so in order to achieve any statistical certainty, astronomers would need to observe dozens or even hundreds of transits, which would take years. Acting on this insight, astronomers started to seek Earths in close orbits around dimmer, colder red dwarf stars, where atmospheric signals will be less drowned out by starlight and transits repeat more frequently. In 2017, astronomers announced the discovery of seven rocky planets around a red dwarf star called TRAPPIST-1. Then in September, the SPECULOOS-2 system emerged as a backup. These stars are close. They're dim and red. They each have multiple rocky planets that transit. And as of the summer, the JWST is up and running even better than expected. It will spend a sizable fraction of the next five years staring hard at these messy globes of rock and chemicals spinning around their strange stars. For theoreticians like Kaltenegger who went from daydreaming of alternate Earths to churning out predictions about their atmospheric chemistry, decades of anticipation have given way to a slow fade-in of squiggly spectra on computer monitors. The goal at the time was to compare spectra from rocky, temperate planets to what Earth's spectrum would look like from far away, seeking conspicuous signals like a surplus of oxygen due to widespread photosynthesis. Kaltenegger's objection was that, for the first 2 billion years of Earth's existence, its atmosphere had no oxygen. Then it took another billion years for oxygen to build up to high levels. And this biosignature hit its highest concentration not in Earth's present-day spectrum, but during a short window in the late Cretaceous Period when proto-birds chased giant insects through the skies. Without a good theoretical model for how Earth's own spectrum has changed, Kaltenegger feared, the big planet-finding missions could easily miss a living world that didn't match a narrow temporal template. She needed to envision Earth as an exoplanet evolving through time. To do this, she adapted one of the first global climate models, developed by the geoscientist James Kasting, which still includes references to the 1970s magnetic-tape era it originated in. Kaltenegger developed this code into a bespoke tool that can analyze not only Earth through time but also radically alien scenarios, and it remains her lab's workhorse.

A sparkling landscape of baby stars. A foamy blue and orange view of a dying star. Five galaxies in a cosmic dance. The splendours of the universe glowed in a new batch of images released from Nasa's powerful new telescope.The unveiling from the $10 billion James Webb Space Telescope began on Monday at the White House with a sneak peek of the first shot — a jumble of distant galaxies that reached deeper into the cosmos than humanity has ever seen. A star-forming region in the Carina Nebula captured in infrared light by the Near-Infrared Camera and Mid-Infrared Instrument. Image / Nasa ESA, CSA, STScI via APYesterday's releases showed parts of the universe seen by other telescopes. But Webb's sheer power, distance from Earth and use of the infrared spectrum showed them in a new light."It's the beauty but also the story," Nasa senior Webb scientist John Mather, a Nobel laureate, said after the reveal. "It's the story of where did we come from." An image of the Southern Ring Nebula being displayed at the Nasa press conference. Photo / Marcio Jose Sanchez, APAnd, he said, the more he looked at the images, the more he became convinced that life exists elsewhere in those thousands of stars and hundreds of galaxies.With Webb, scientists hope to glimpse light from the first stars and galaxies that formed 13.7 billion years ago, just 100 million years from the universe-creating Big Bang. The telescope also will scan the atmospheres of alien worlds for possible signs of life."Every image is a new discovery and each will give humanity a view of the humanity that we've never seen before," Nasa administrator Bill Nelson said, rhapsodising over images showing "the formation of stars, devouring black holes".Webb's use of the infrared light spectrum allows the telescope to see through the cosmic dust and see faraway light from the corners of the universe, he said.

A US government report on UFOs has said there was no clear explanation for the unidentified aircraft, but did not rule out extra-terrestrial origin. Hundreds of millions of dollars have been invested into searching for signs of alien intelligence. Ed Butler speaks to Lisa Kaltenegger, an astronomer at Cornell University, who has analysed the closest, most likely planets to support alien life. If, or when, we do make contact what could we trade with our new neighbours? David Brin, a science fiction writer and astro-physicist says our culture would be the most easily exchanged aspect of our civilisation. And what about making money on Earth from the continued interest in aliens? Juanita Jennings is the public affairs director for the town of Roswell, New Mexico. The site of the most famous UFO sighting. (Picture: a UFO over the Mojave desert, USA. Credit: Getty Images.)

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?

The object was round and irregular, he said, and it would suddenly plummet tens of thousands of feet before soaring right back up, he said. Cobb, an 88-year-old Korean War combat veteran, spotted the mysterious object while sitting at Silver Creek Airport in Morganton, where he visits each day to check on the 1940 Piper Cub he keeps in a hangar. Cobb said he finally pulled out his iPad and took photos of the flying object and its “opaque” center. It was 11:18 a.m. June 12. “It was hard to tell the size,” he said, although he distinctly recalled the craft dropping at times to maybe 15,000 feet before shooting back up to at least 30,000 feet. “The fact that it could zoom up almost out of sight” made this no ordinary object, he's convinced. The craft also was “flying parallel” during the 15 to 20 minutes he watched it, he said, so it couldn't have been a comet. “Comets come toward you,” he said. This object “always pointed north.” Mysterious lights in night sky baffle Hawaii residents. ‘What in the world is this?' Link: https://www.sacbee.com/news/nation-world/national/article246732446.html Mysterious lights flying across the night sky over the weekend baffled Hawaii residents. While social media was abuzz with speculation of UFOs, scientists think they know what's responsible. Kuuipo Kanawaliwali captured video of the lights as they passed under the moon on Saturday night. “I started videotaping and when they got closer,” Kanawaliwali told KHON, “I start freaking out because I'm like, ‘Oh, what in the world is this?'” Sheri English also captured video of the lights as they sailed overhead. “We didn't know what it was, where it came from,” English told KHON. “It just appeared. It was actually (a) very eerie, eerie feeling.” John O'Meara, the chief scientist at W.M. Keck Observatory in Hawaii, says the lights were from a Chinese rocket booster used to launch a Venezuelan communications satellite in 2008, Maui Now reported. “That booster has been orbiting around the Earth, but its orbit has been decaying and eventually decayed enough to get slowed down by the atmosphere and reentered in over the Pacific,” O'Meara told the news outlet. “Space junk falls in all the time.

The man, an elderly Southend resident, said the sighting from Kiel on October 13 was not prolonged and the apparent movement of the phenomenon couldn't confirm whether it was several lighted objects or just one object with multiple lights. He added: ‘We were watching seals on Kiel beach when suddenly I noticed a line of lights, low down but very intense. I'm not particularly a believer in [extra-terrestrial] UFOs but watching those lights made me feel very strange.' Aliens on 1,000 nearby stars could see us, new study suggests Link: https://www.livescience.com/aliens-spot-earth-exoplanets.html There are about 1,000 star systems where aliens, if they existed, could be watching us from afar, new research suggests. Those 1,004 star systems are in a direct line of sight to our planet, and close enough to us that they could not only detect planet Earth, but also chemical traces of Earthly life. "If observers were out there searching, they would be able to see signs of a biosphere in the atmosphere of our Pale Blue Dot," Lisa Kaltenegger, a Cornell University astronomer and lead author of the paper, said in a statement. Within 326 light-years, the researchers found, there are 1,004 with vantage points to spot Earth. Of those, 508 have viewing angles that would give them at least 10 hours of observational data every time Earth passed between that location and the sun — ideal conditions for spotting this little rocky planet and the signs of life in its atmosphere. "Only a very small fraction of exoplanets will just happen to be randomly aligned with our line of sight so we can see them transit." said Lehigh University astrophysicist Joshua Pepper, co-author of the paper, in the statement. "But all of the thousand stars we identified in our paper in the solar neighborhood could see our Earth transit the sun, calling their attention." Show Stuff Join the episode after party on Discord!

Is there life in the universe beyond planet Earth? It's the question everyone, including Alan Alda, wants to understand. In this episode, Alan asks Dr. Lisa Kaltenegger, the head of the world-renown Carl Sagan Institute, about life in the cosmos. What Dr. Kaltenegger has to say is surprising and inspiring. Before you stare up at the sky tonight, be sure to hear what Dr. Kaltenegger has to say about which of the billions of planets might be more like ours than we ever thought possible.  Support the show.

Extinction Rebellion is in the news with its stated aim of civil disobedience and protest, and goal to compel governments around the world to act on the climate crisis. Meanwhile, the UK government this week announced that it was overruling its own Planning Inspectorate, by approving in principle new gas-fired turbines at the Drax power station in North Yorkshire. The Inspectors had advised that the new developments would undermine UK climate policies on carbon emissions. In the UK we are committed to reaching net zero carbon emissions by 2050, in order to comply with our ratification of the Paris agreement, which aims to limit global temperature rise to 1.5 degrees. So what are we to do? Are the government policies and commitments enough, and are we sticking to them? Adam Rutherford discusses these questions with Jim Skea, Professor of Sustainable Energy at Imperial College, London, and co-chair of the Working Group tackling reducing emissions of greenhouse gases, part of the Intergovernmental Panel on Climate Change. This week has been the annual jamboree and drama of the Nobel Prizes: the announcements of the biggest gongs in science. The Physiology or Medicine Prize went to William Kaelin from Harvard University, Sir Peter Ratcliffe from the Crick Institute in London and Gregg Semenza from Johns Hopkins University for their work on how the body responds to changing oxygen levels. The Physics Prize went to James Peebles of Princeton for cosmological discoveries, and Michel Mayor and Didier Queloz, then at the University of Geneva, for the 1995 discovery of the first exoplanet, 51 Pegasi b. And the Chemistry Prize was awarded for the invention of something that we utterly rely on every day, the lithium battery. The winners are John Goodenough, University of Texas at Austin, Stanley Whittingham, State University of New York, and Akira Yoshino of the Asahi Kasei Corporation in Japan. These awards offer plenty to discuss, so Adam is joined by Lisa Kaltenegger, Director of Carl Sagan Institute & Associate Professor of Astronomy, Andrew Pontzen, Professor of Astrophysics at University College, London, and reporter and presenter Marnie Chesterton, who spent some time with chemistry laureate John Goodenough.

At the turn of the century just a couple planets around other stars had been discovered. Now more than 4000 have been found. Lisa Kaltenegger specializes in finding the fingerprint of life in the faint light that reaches us from those stars and planets.

Who can look out into space and not ask the age-old question: Are we alone in the universe? Astronomers have already identified dozens of planets beyond the edges of our solar system which could be like our own Earth. Join astrophysicist Lisa Kaltenegger as she explains the different methods astronomers use to detect exoplanets orbiting distant stars, what these planets would need to support life, and how Earth and its range of species might serve as a Rosetta Stone—a key to detecting the existence of extraterrestrial life.

The submarine famously named Boaty McBoatface is deployed this week for its first mission to examine a narrow submarine gap in the South Atlantic. Mike Meredith of the British Antarctic Survey tells Adam Rutherford how this research into the behaviour of deep water at this crucial point in the oceans will help us answer key questions about global ocean temperature flows. Some close-quarter flying in the wake of a jet has provided new insights on reducing aircraft pollution. Richard Moore at NASA Langley in Virginia describes how he's taken to the skies to measure gasses emitted by new biofuels to assess their impact in reducing carbon soot particles, aircraft contrails and climate-changing cloud formations across the sky Angela Saini visits the Bodleian Library in Oxford where the Bakhshali manuscript which contains possibly the very first graphical representation of the number zero is finally being carbon dated so we can better understand its scientific importance And the habitable zones around stars in our the universe just got a whole lot bigger. Lisa Kaltenegger of the Carl Sagan Institute reveals how the presence of volcanoes pumping out hydrogen has a significant warming effect on planets, and increases the range of the so called Goldilocks Zone Producer: Adrian Washbourne.
