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:
► “Sipping with Kipping” by Jeff Xie and Gabrielle Englemann-Suisse:
► “Astrometry & Exoplanets” by Shreyas Vissapragada and Briley Lewis:

Cool Worlds Lab


Astronomy, exoplanets, astroengineering, the search for extraterrestrial life & intelligence, futurism and interstellar travel.

The Cool Worlds Lab (, 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. Content is primarily written, produced and presented by David Kipping, but regularly features his students and visitors as guest presenters.
