Through The Wormhole Season 1 Episode 6 Are We Alone? | Morgan Freeman

Aliens almost certainly do exist. So why haven't we yet met E.T.? It turns out we're only just developing instruments powerful enough to scan for them, and science sophisticated enough to know where to look. As a result, race is on to find the first intelligent aliens. But what would they look like, and how would they interact with us if we met? The answers may come to us sooner than we imagine, for one leading astronomer believes she may already have heard a hint of their first efforts to communicate.

Featuring astrobiologist Lynn Rothschild of NASA Ames Research Center, astronomer Jill Tarter, physicist and SETI projects affiliate Paul Davies, astronomer Geoff Marcy and his student Paul Butler, and space scientist William Borucki. This episode talks about the Murchison meteorite, the Allen Telescope Array, 51 Pegasi b, and the Kepler Space Telescope mission.
