    If we ever do receive a message from outer space, we´ll want to know what kind of aliens sent it. SETI researcher Seth Shostak says we shouldn´t expect them to be anything like us – in fact, they might not be biological at all,

    New research indicates that most of the 'hot Jupiter' planets that have been discovered beyond our solar system were likely destroyed by their stars long ago. The study provides new insight into the formation and evolution of planetary systems and will help astrobiologists determine where

    Astronomers have measured the temperature of a young gas-giant planet and found that its atmosphere is unlike that of any previously studied extrasolar planet. Such observations help astrobiologists understand the properties of extrasolar planets and will aid in the search for habitable worlds beyond our

    A new study using data from the Spitzer Space Telescope has shown that double-star systems may not be good places to search for life. A large amount of dust in three systems with close-orbiting stars could be the result of tremendous planetary collisions, indicating such
