The Worlds of TRAPPIST-1
b'The discovery of seven, Earth-sized planets in a nearby solar system was announced last week. Astrophysicist and planetary scientist Sara Seager was part of the NASA press conference. Now she joins us to share her excitement about this find that includes three planets in the habitable zone. Digital Editor Jason Davis says we\\u2019re a little closer to orbiting and landing on Jupiter\\u2019s moon Europa. Bill Nye comments on SpaceX plans to send two people around the moon in 2018. And it\\u2019s not too late to catch a high and bright Venus according to What\\u2019s Up astronomer Bruce Betts.
