NASA recently discovered seven Earth-like exoplanets orbiting a star 40 light years away from Earth. Any one of the planets could possibly harbor life, but the three outermost planets lying in the star's "habitable zone" have the most likely chance. Whether they do or don't, this discovery will give scientists insight about the conditions under which life is able to evolve. We'll talk about this discovery and other space news this hour with a panel of guests.

Guests:
Michael Werner, project scientist, NASA's Spitzer Space Telescope
Paul Sutter, astrophysicist, Ohio State University, Chief Scientist, COSI
