UFO sightings happen all the time – maybe even today! What would happen if top-secret UFO information leaked from the government? Neil deGrasse Tyson and co-host Harrison Greenbaum investigate the obvious pitfalls and enticing questions that come with UFO sightings. Plus, Neil sends his own message to any aliens out there listening.

Once again, at the AAS Meeting in Hawaii, I got a chance to sit down with another astronomer to talk about their research. This time it was Dr. David Kipping from Columbia University's Cool World's Lab. We talked about how easy it'll be for aliens to know our planet is inhabited, and some ways we might be able to hide the evidence of our existence.

At the American Astronomical Society's meeting Honolulu I got a chance to talk with Adam Frank about new research he's worked with Caleb Scharf, Jonathan Carroll-Nellenback and Jason Wright about the Fermi Paradox. They calculated how difficult it would be for aliens traveling at 10% the speed of light to settle the entire Milky Way, and it turns out, it's not as simple as you might think.

Thirty-five years ago, a group of entrepreneurs and scientists founded the SETI Institute – the first scientific institute dedicated to the search for extraterrestrial life in the universe. We’re excited to commemorate this anniversary. We invited SETI Institute co-founder Jill Tarter and 2018 Drake Award Recipient Vikki Meadows to discuss the challenges and possible future strategies for the detection of life. Initiated by Jill Tarter in 1990s, Project Phoenix marked the first systematic search for technosignatures. Today, the Allen Telescope Array and Laser SETI are driving our technosignature search. The discovery that exoplanets are common has radically changed our view of the universe. The likelihood that there are habitable worlds elsewhere in the universe seems more plausible than ever before. Astronomers, including Vikki Meadows, are developing new instruments to help search for life on other planets. By analyzing data from exoplanets and identifying biosignatures, we will be able to search for habitable planets and the presence of life. Which approach will discover the first evidence of extraterrestrial life? Will technosignatures or biosignatures confirm our hypothesis that life exists outside our watery, shimmering planet and that, indeed, we are not alone? Molly Bentley, the co-host and producer of the radio program and podcast, Big Picture Science, will be the moderator.

New videos DAILY: https://bigth.ink Join Big Think Edge for exclusive video lessons from top thinkers and doers: https://bigth.ink/Edge ---------------------------------------------------------------------------------- Are UFOs actually alien spacecraft visiting Earth? They might be, says Neil deGrasse Tyson, but if you want to make that claim you better bring the evidence to support it.Eyewitness testimony is the lowest form of evidence. To measure what is true or not true in the world, we require data -- and when it comes to alien appearances, it's as astronomer Carl Sagan said: "Extraordinary claims require extraordinary evidence."So what can you do to prove your alien abduction story? Take selfies, live-stream video to the internet, and if you happen to find yourself in a spacecraft getting your "gonads poked", then grab an item from the alien lab as evidence before they release you back on Earth. Neil deGrasse Tyson wants to believe, but not until he sees the data. ---------------------------------------------------------------------------------- NEIL DEGRASSE TYSON Neil deGrasse Tyson was born and raised in New York City where he was educated in the public schools clear through his graduation from the Bronx High School of Science. Tyson went on to earn his BA in Physics from Harvard and his PhD in Astrophysics from Columbia. He is the first occupant of the Frederick P. Rose Directorship of the Hayden Planetarium. His professional research interests are broad, but include star formation, exploding stars, dwarf galaxies, and the structure of our Milky Way. Tyson obtains his data from the Hubble Space Telescope, as well as from telescopes in California, New Mexico, Arizona, and in the Andes Mountains of Chile.Tyson is the recipient of nine honorary doctorates and the NASA Distinguished Public Service Medal. His contributions to the public appreciation of the cosmos have been recognized by the International Astronomical Union in their official naming of asteroid "13123 Tyson". Tyson's new book is Letters From an Astrophysicist (2019). ---------------------------------------------------------------------------------- TRANSCRIPT: NEIL DEGRASSE TYSON: There are many people who see things in the sky and are sure – they can't explain it, so they're sure it's aliens visiting. Well, if you were really, really sure of that, you are not likely to write me a letter. Unless you're writing me a letter to convince me of your point of view. But that doesn't make for a fertile exchange. If you see lights in the sky and you don't know what they are and you want further insight on what they could be and write me a letter, that's a meaningful exchange. If you can't explain what it is and it's flying and it's an object, it's an unidentified flying object, period. You just said you don't know what it is so that sentence should not continue beyond that phrase. You can't say I don't know what it is, therefore, it must be aliens visiting from another planet. If you don't know what it is it therefore must not be anything. Okay, so maybe we are getting visited by aliens daily. In all of these sightings, it's aliens. I don't have a problem with that. My issue is what you are presenting as evidence in support of that claim. If it's entirely grounded in your eyewitness testimony you need to know that eyewitness testimony on the totem of weight of evidence it is at the bottom. A little scary because in the court of law it's considered pretty high evidence. People say, "I need a witness!" No, you want data. That's what you really want. You want information that didn't have to pass through someone's sensory system so that you can minimize bias, delusion, the filtering that we always do as the world outside of us comes through our senses for us to then decide what is and what is not going on around us. It's why we invented science. So that we wouldn't have to depend on our senses as the ultimate measure of what is or is not true in the world. Science and its methods and tools. The telescope, the microscope, the recorders, chart recorders, all of this. So, the best thing is—and by the way, I don't care what your pedigree is. I don't care if you're a military colonel, pilot, Air Force. Are you human? That's all that matters. After that give me better evidence. And yes, Carl Sagan's famous dictum, "extraordinary claims require extraordinary evidence." So the best thing is to drag the alien into town square and you'll be rich and famous overnight. You don't have to argue with me. I'm not stopping you. Go ahead. But do you know what's more significant than that fact is that today, worldwide, we are uploading to the internet a billion photographs a day. Everyone has a camera and a video camera. Remember all those reports of pe... For the full transcript, check out https://bigthink.com/videos/neil-degrasse-tyson-want-to-prove-aliens-exist-do-this

Are we ready for what’s out there? An irreverent look at whether we should in fact, be announcing ourselves to the universe. Seth Shostak directs the search for extraterrestrials at the SETI Institute in California—trying to find evidence of intelligent life in space. He is also committed to getting the public, especially young people, excited about astrobiology and science in general. Seth is also the host of “Big Picture Science,” the SETI Institute’s weekly radio show. The one-hour program uses interviews with leading researchers and lively and intelligent storytelling to tackle such big questions as: What came before the big bang? How does memory work? Will our descendants be human or machine? What’s the origin of humor? Big Picture Science can be found in iTunes and other podcast sites. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

With all the spacecraft we are sending to Mars, we might actually run into some Martians. Are we prepared for such an encounter?

The SETI Institute's Nathalie Cabrol walks you through what it's like to prepare for a month-long field expedition to the mountains of Chile.

Today, we discuss the possibility of a more idle but settled civilisation: one that remains utterly restricted to the boundaries of their home planet and sees no point whatsoever in traversing the stars, even if they have the ability to do so, as a solution to why we aren't seeing any alien civilisations in the night sky. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://www.youtube.com/watch?v=Uen6euyVYFM Music: “Cylinder Five” by Chris Zabriskie “So Many Stars” by Miguel Johnson “Sirius” by Sergey Cheremisinov Credits: Vidsplay.com

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Discussion of advanced extraterrestrial civilizations often hinges on the idea that they may have ascended to a higher state or higher level of reality, and lost interest in us and the rest of the galaxy. While we can't know what technologies or enlightened paths they might have available, we can ask how realistic the portrayals of those aliens might be, and if this notion make sense as a Fermi Paradox solution.

Does intelligent alien life exist? Answering the question of are we alone has turned out to be a bit more difficult than was originally envisioned when SETI first began decades ago. At first it was a matter of looking for giant omnidirectional beacons blasting out high energy messages, much like what we saw in the movie contact. But as we’ve gone through the process of searching, it’s becoming evident that such a scenario was in a way wishful thinking. We have seen no such unambiguous beacons, and thinking on just why a civilization would expend massive amounts of energy on a signal has changed. It's very likely to be far more subtle than that, and that any intentional message would be beamed directly at us. But beacons aren’t the only game in town. Since the advent of SETI, other technosignatures beyond radio have been thought of. Now we can look for laser emissions, industrial chemicals in the atmospheres of exoplanets, Dyson swarms, and a host of other signatures that would tell us if there are alien civilizations out there. Where is intelligent life in the universe? John is joined with Isaac Arthur to discuss the Fermi paradox, to try and answer where all of the intelligent life is in the universe, and look at what possible techno signatures are most likely. Dyson spheres and Dyson swarms, von neumann probes, and machine civilizations.

Earlier this year, Verge Science went hunting for space dust on a rooftop in Brooklyn. The hunt turned up some promising samples, but looking at them under a microscope led to inconclusive results — even from the world’s foremost micrometeorite hunter. To get to the bottom of things, we took a trip to NASA's Johnson Space Center to learn how to verify suspected space samples and to learn about what these tiny specks could teach us about the secrets of the universe.

People are always worried that alien civilizations will detect the transmissions from our old radio shows and television broadcasts, and send in the invasion fleet. But the reality is that life itself has been broadcasting the existence of life on Earth for 500 million years. Blame it on the plants. In addition to filling the atmosphere with oxygen, plants give off a very specific wavelength visible in infrared radiation. It’s the kind of signal that other civilizations could search for as they’re scanning the galaxy. It’s what we’ll be looking for too. But don’t just blame the plants. Other forms of life have been giving off signals too, signals we can search for as we discover new exoplanets and wonder if they have life there.

Watch Kalind Carpenter and Morgan Cable from JPL present the Exobiology Extant Life Surveyor or EELS robot architecture which is designed to carry the latest instruments into dynamic arenas in search of life. EELS is adaptable to traverse ocean world inspired terrain, fluidized media, enclosed labyrinthian environments and liquids. It is a snake-like self-propelled endoscope form comprising serially-replicated segments with encapsulated locomotion and bending. This lecture was presented at the Keck Institute for Space Studies on July 15, 2019. Speakers' Biography: Kalind Carpenter is a Robotics Engineer in the robotic Vehicles and Manipulators group at JPL. The lab he has helped create focuses on rapid technology development and end effectors specifically tailored to gripping and extreme surface mobility. He is the principal investigator (PI) of the Exobiology Extant Life Surveyor (EELS), a snakelike robot aimed to access Enceladus’s ocean through an active plume. He has collaborated on four patents including two based on his thesis research and has three more provisional patents in place. Dr. Morgan Cable is a Research Scientist at the NASA Jet Propulsion Laboratory in Pasadena, California. She worked on the Cassini Mission as a Project Science Systems Engineer, and is currently a member of the Project Science Team for the Europa Lander mission concept. Morgan’s research focuses on organic and biomarker detection, through both in situ and remote sensing techniques. While earning her Ph.D. in Chemistry at Caltech, she designed receptor sites for the detection of bacterial spores, the toughest form of life. As a NASA Postdoctoral Fellow at JPL, Morgan developed novel protocols to analyze organic molecules such as amines and fatty acids using small, portable microfluidic sensors. Currently Dr. Cable performs laboratory experiments to study the unique organic chemistry of Titan, a moon of Saturn. She and colleagues were the first to discover a co-crystal, the equivalent of a ‘hydrated mineral’, made exclusively of organics that may exist on Titan’s surface. This work has led to the inception of a new field, Titan ‘petrology’. Morgan also conducts field work in extreme environments on Earth, searching for life in places such as the Atacama Desert, the summit of Mt. Kilimanjaro and the lava fields in Iceland.

NASA plans to send an unmanned drone to Titan, Saturn’s largest moon. Titan resembles an early Earth in several ways, containing a thick atmosphere, liquid lakes and rivers on its surface, and an underground ocean of water.
