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

Water Eruptions on Europa Mean that Conditions Are Ripe for Life

Jupiter's moon Europa is covered in a thick layer of ice, but it has a turbulent ocean that lies beneath. Today astronomers announced that new observations show this water is erupting in massive plumes like water volcanoes. It's a discovery that could have serious implications for Europa's potential to harbor life. » 12/12/13 8:00am 12/12/13 8:00am

Two Billion Reasons Why We're About to Find Earth 2

Planet-hunting scientists announced today that 22% of sunlike stars in the Milky Way are orbited by potentially habitable, Earth-size worlds. This remarkable finding indicates that there may be as many as two billion planets in our galaxy suitable for life — and that the nearest such planet may be only 12 light-years… » 11/04/13 1:42pm 11/04/13 1:42pm
