Cool Worlds

Cool Worlds

Space, astronomy, exoplanets, astroengineering and the search for extraterrestrial life & intelligence.

The Cool Worlds Lab (http://coolworldslab.com), based at the Department of Astronomy, Columbia University, is a team of astronomers seeking to discover and understand alien worlds, particularly those where temperatures are cool enough for life, led by Professor David Kipping.

    Freakish One-Offs in Astronomy

    Signup for your FREE trial to The Great Courses Plus here: http://ow.ly/x8l230rIoRs - thank you to our sponsors! New research! One-offs... there's something about them, whether it be the first interstellar asteroid or a star behaving in an unprecedented way. These "black swans" capture our attention and imagination but interpreting them is challenged by the inherent scarcity of data. Perhaps no case encapsulates this more than the famous 1977 Wow Signal. Join us today as we discuss our new paper on Black Swan Theory with consequences for the Wow signal.

    The Truth About JWST Detecting Alien Life...

    JWST is the pinnacle of our astronomical aspirations, the most sensitive telescope ever built by human hands. But can this feat of engineering resolve a question which has haunted us since the dawn of civilization - are we alone? So let's explore whether JWST could detect signatures of biology on another world, and if so under what conditions? Sponsored by Ground News, head to https://ground.news/coolworlds Written and presented by Prof David Kipping, edited by Jorge Casas.

    Extremely Large Telescopes | Moiya McTier

    Extreme!!! Everyone loves extreme stuff and astronomers are no different. When it comes to telescopes, size matters. Moiya McTier goes through the biggest telescopes around and what astronomers are planning for in the next few decades. But increasingly astronomers are realizing that we can't just put telescopes wherever we want, the locals may not want us to construct gigantic machines on what can sometimes be sacred ground... ::More about this Video:: ► Green Bank Observatory: http://greenbankobservatory.org ► GMT: https://www.gmto.org ► TMT: https://www.tmt.org ► E-ELT: https://www.eso.org/public/usa/teles-instr/elt/ ► Arecibo drone footage by DJI 101: https://www.youtube.com/watch?v=yBLgYXytaP0 ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Background music by Thomas Bergersen "Final Frontier": http://www.thomasbergersen.com A note on comments- we always love to engage with you down below but aggressive, inappropriate, hostile and trolling comments directed at our junior scientists especially will be removed. ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

    Bayesian Worlds

    One branch of statistics, called Bayesian statistics, is becoming increasingly important in detecting new planets. Emily Sandford, a second-year graduate student with the Cool Worlds Lab at Columbia, explains our new paper and the concept of Bayesian priors, hopefully providing astronomers the tools we need to analyze new discoveries! ::More about this Video:: ► Kipping & Sandford (2016), "Observational biases for transiting planets": http://arxiv.org/abs/1603.05662 ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

    Semantics

    Lately there has been a growing push-back from the exoplanet community for astronomers to stop using the phrase "Earth-like". In this video, we get into the arguments being made and some reasons why I am personally finding the movement unpalatable. This is a topic ripe for public discussion so please watch through then let us know in the comments section what your opinion is!

    The Habitable Zone: Undergraduate Outreach Project

    This semester I taught "Exoplanets & Astrobiology" at Columbia and decided to do something a bit non-traditional and ask my class to make outreach videos in any style they want about a topic we covered in class. This video, by Elliotte Jun Beom Lee, Natalie Gaisser & Huiying Zhang was voted the class favorite and so I decided to upload it on the Cool Worlds channel to share with everyone!

    Is It Possible to Learn The Language of Planets?

    Could we learn to "speak planet"? Computational linguistics is now found in your smart phone, car and speakers, making sense of our speech and text. Could these same algorithms make sense of exoplanets? Join us today as we explore a radical new research idea recently published by the Cool Worlds Lab. Written and Presented by Dr Emily Sandford.

    How to Characterize Proxima b's Atmosphere

    As regular watchers of the channel may remember, this summer astronomers announced the discovery of a potentially Earth-like planet orbiting our nearest star, Proxima Centauri. Sadly, research at the Cool Worlds Lab was unable to find any evidence that Proxima b transits its star, which is a blow for those hoping for near-term characterization of its atmosphere. But! Dr Jayne Birkby comes to the rescue and explains here how an alternative technique should work if we can wait a few years!
