Cool Worlds

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

The Cool Worlds Lab (http://coolworlds.astro.columbia.edu), 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.
