EXTRATERRESTRIAL LIFE

Breakthrough Listen is undertaking a comprehensive survey of the Galactic Center, which will be one of the most sensitive SETI surveys ever conducted. Our new paper outlines the strategies we're using, and results from some of the initial observations.

In this week's questions show I explain why we could be first in the Universe, do galaxies flip or spin, did I pick a good career? And more. 00:00 Start 00:47 Are we first in the Universe? 03:01 Do galaxies flip end over end? 04:28 Bro, get a better career 06:46 How much longer can SLS going? 10:33 Did I watch Ingenuity fly? 12:08 Am I looking forward to the movie version of the Three-Body Problem? 13:42 Does it make sense to try and watch a rocket launch? 16:32 Could we build space elevator on Mars. 18:38 What one mystery about space would I like to know? 21:00 Why don't we take the low gravity on Mars seriously? 24:47 What astronomy career is good if you're bad at math? Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here. 🚀 OUR WEBSITE: ════════════════════════════════════ https://www.universetoday.com/ 🚀 PODCAST LINKS: ════════════════════════════════════ RSS: https://universetoday.com/audio iTunes: https://universetoday.com/itunes Spotify: https://universetoday.com/spotify 🚀 EMAIL NEWSLETTER: ════════════════════════════════════ Read by 50,000 people every Friday.

Seth Shostak, senior astronomer at the SETI Institute, is our guest on this Cosmic Conversation. He discusses new approaches to looking for E.T., including the latest efforts to uncover signals from extraterrestrial intelligence, as well as some disturbing ideas that could change the way we hunt for cosmic company. Also, what happens if we actually manage to detect someone or something out there? Would that radically change our own society, or merely be an interesting story for a week or two? - - - 🙌 Now More Than Ever, We Need Your Support.

We THINK there should be thousands of them... but we've so far found proof of NOTHING. So, what gives? In this video, we discuss 4 possible answers to the Fermi Paradox!

Over the last few decades, scientists have found thousands of planets beyond our own. Some of those planets might be habitable, and perhaps even inhabited already; but how can we tell? Clara Sousa-Silva, a fellow at the Center for Astrophysics | Harvard & Smithsonian, looks for signs of life on other planets using astronomical tools to detect faint signals emitted by potential alien biospheres. In this presentation, Clara draws on her experience investigating strange molecules on strange planets, such as her recent work exploring the possibility of phosphine on Venus, answering the question: "Would we know life if we saw it?"

Sixty years ago Frank Drake wrote down an equation that has become one of the most famous in astronomy - the Drake Equation. This formula, aiming to estimate the number of alien civilizations communicating within the galaxy, has been celebrated, abused and criticized. Today, we are taking a deep dive into this special equation in a two part special. Written and presented by Prof David Kipping. Thanks to Jason Wright and Nadia Drake for help with this video.

On this episode of StarTalk Radio, Neil deGrasse Tyson and comic co-host Chuck Nice are answering a grab bag full of fan-submitted Cosmic Queries on topics ranging from dark matter to the end of the universe. What is dark matter? Could it be another universe’s gravity bleeding into our own universe? You’ll learn what the leading possibilities are to explain dark matter. Neil and Chuck dive into field theory. Discover more about our expanding universe. We discuss our eventual collision with the Andromeda galaxy. Neil explains how the universe might have removed chapters from its own history, forever hiding it from us. What would it be like if you grew up on Venus? Because of the thick atmosphere, would you be aware of other places in the galaxy? We ponder if we can use gravitational waves to communicate with life in other universes. You’ll also find out how the electromagnetic spectrum serves as a window to the universe. To kick off the last segment, Neil gets asked a big question: How does it all end? You’ll hear why the universe will end not in a bang, but, with a whimper. You’ll also hear about “The Big Rip.” Lastly, we explore the SN 1987A – the most recent supernova witnessed by humans. All that plus, we investigate the relationship between science and art.

Finding intelligence in the cosmos might be done simply by paying attention. While SETI scientists look for radio or optical signals, the astronomy community is perennially on the lookout for all types of cosmic phenomena. One example of the latter is the discovery, three years ago, of what was thought to be a previously unknown asteroid. While asteroids are enormously commonplace in our solar system, this object, christened Oumuamua, is clearly from someone else’s solar system. Harvard astronomer Avi Loeb has suggested that Oumuamua might not be an asteroid at all, but a type of interstellar craft, sent our way by extraterrestrials. Why does he think this, and what is the larger lesson we should heed in our search for alien intelligence? If you like SETI Live, or just like science, support the SETI Institute!

The search for the mysterious planet nine continues as Mike Brown and Konstantin Batygin get closer to finding it. What would planet 9 be like and where in the solar system could it be? Also, what would alien life look like? Humanoid or something we couldn't even imagine. John Michael Godier discusses planet 9 and the fermi paradox with Parallax Nick. Parallax Nick, is a science presenter and YouTuber with a channel that focuses on sharing his thoughts and knowledge of science, history and the multiverse at large.
