    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! Let us know what you think and if you have any questions about habitable-zones.You can check out some of the other great videos made by class here:► "What is a Planet by the Left-Handed Sneutrinos" by Leah Hays, Greg Humphries & Kaitlyn Loftus: https://www.youtube.com/watch?v=W4U9kd9NjaA► "Sipping with Kipping" by Jeff Xie and Gabrielle Englemann-Suisse: https://www.youtube.com/watch?v=W4U9kd9NjaA► "Astrometry & Exoplanets" by Shreyas Vissapragada and Briley Lewis: http://www.showme.com/sh/?h=7osiO8m::More about this Video::► Kopparapu et al.

    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.
