What's New in Lunar & Planetary Science

NASA has announced new details on the discovery of a planetary system by researchers at the University of Liege in Belgium. The system, called TRAPPIST-1, contains 7 roughly Earth-size planets orbiting close to an ultra-cool dwarf star. Three of the planets appear to be in the habitable zone, potentially having liquid water and conditions amenable to life. For more information, see the NASA press release.
