About

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.

Video Description

Visit our sponsor, Private Internet Access to get digital privacy for $2.08/month: https://www.privateinternetaccess.com/CoolWorlds The search for alien intelligence is usually a framed as a search for life around other stars. But some have suggested that we should look within the Solar System instead - seeking so-called "Lurkers", alien probes sent here to monitor us. Today we explore this interesting idea, the motivations behind it and where we might actually try surveying.
