s02e20: Thomas Barclay: In Search of Alien Worlds
Update: 2019-03-01
Description
Are we alone in the Universe? This is a question that has puzzled countless generations. While we are still unable to say whether there is life out there we are beginning to think about whether there are planets that remind us of home. The Kepler spacecraft has been used to identify several planets in the habitable zone of other star - a region around a star where a planet could host liquid water at its surface given an appropriate atmosphere. Of particular note is Kepler-186f which is an Earth-sized planet that orbits within the habitable zone of a star that is smaller and cooler than the Sun. This talk will focus on the search for Earth-like worlds, discuss what we know about the planets we have found and look at what we don't know right now but hope to learn from future NASA missions.
