Jupiter May Have Destroyed The Solar System's First Planets

It is becoming increasingly obvious that our Solar System — with its inner collection of small rocky planets and an outer region buffeted by gas planets — is quite uncommon. According to a remarkable new study, the reason may have to do with Jupiter and an ancient migratory journey that kickstarted the destruction of… » 3/24/15 8:00am 3/24/15 8:00am

Freakishly Old System Of Planets Hint At Ancient Alien Civilizations

This suggests that terrestrial planets have appeared throughout most of the Universe's 13.8 billion year history — a potential indication of just how ancient some extraterrestrial civilizations could be. » 1/27/15 8:00am 1/27/15 8:00am

We've Found A Hidden Ocean On Enceladus That May Harbor Life

It's turning out that the outer reaches of the solar system may be more hospitable to life than we ever imagined. Gravity measurements made by Cassini have confirmed that Enceladus, a tiny moon orbiting Saturn, hosts a subsurface ocean in its southern latitudes. Astronomers are now saying it's potentially habitable. » 4/03/14 11:00am 4/03/14 11:00am

New study dramatically changes where we believe aliens might live

A team of astrobiologists has redefined conventional notions of where life can exist within a solar system. They've suggested that life could exist inside planets with inhospitable surfaces. Dubbed "subsurface habitable zones," this new definition of habitable zones means that alien life may be far more prevalent than… » 1/13/14 12:20pm 1/13/14 12:20pm
