    Kepler 62 Discovery Hangout with Sara Seager

    by Tony Darnell

    The exciting discovery from the Kepler science team yesterday of a system of planets around the smallish star Kepler 62 had the internet buzzing late in the day.

    Most of the excitement stemmed from the fact that TWO of the five planets in the system lie within the star's habitable zone and are roughly the size and mass of Earth.  The two planets are Kepler 62 e and f and are closer to each other than Earth is to Mars!

    It isn't known if the planets have atmospheres, but there are some really interesting things in this system.

    I spoke with Dr. Sara Seager, an astronomer and planetary scientist from MIT, about the discovery. We talked about not just the Kepler 62 system, but the broader concept of habitablity as well.

    Enjoy and please let us know what you think!
