New Evidence Suggests Pluto Has An Ocean Beneath Its Surface

Astronomers believe that Pluto and its moon were the result of two massive objects slamming into each other. The resulting gravitational dynamic may have warmed the interior of Pluto, creating an ocean comprised of liquid water. Remarkably, this underground sea could still be there. » 4/15/14 11:00am Yesterday 11:00am

Astronomers May Have Spotted Waves On Titan's Seas

Other than Earth, Titan is the only celestial object in the solar system capable of fostering stable liquids on the surface. But now, after years of searching, scientists may have detected waves rippling on its seas — which, if confirmed, would be the first discovery of its kind. » 3/18/14 6:40am 3/18/14 6:40am

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

What a Habitable Planet Twice the Size of Earth Would Be Like

To date, astronomers have catalogued over 1,000 exoplanets — some of them rocky and parked within their host star's habitable zone. But a good portion of these planets are bigger than Earth, prompting us to ask: What would it actually be like on a habitable planet twice the size of ours? » 12/04/13 8:40am 12/04/13 8:40am

It may be easier to find alien life on Europa than we thought

Jupiter's moon Europa is one of the more intriguing candidates for extraterrestrial life in our solar system. New models suggest that its ice-covered waters are turbulent near the lower latitudes, giving rise to its chaotic equatorial landscapes. Intriguingly, these warm waters may make it easier for life to make it to … » 12/03/13 9:55am 12/03/13 9:55am

A Dramatic Glimpse of Mars as it Appeared Billions of Years Ago

To illustrate how radically the face of Mars has evolved over the past several billion years, researchers from NASA's MAVEN mission have put together a revealing new video showing a Red Planet that was once anything but. » 11/14/13 1:13pm 11/14/13 1:13pm

Why it might be possible to go snowboarding on Mars

NASA scientists think that sliding chunks of frozen carbon dioxide — dry ice — may be responsible for creating track marks on some Martian sand dunes. Which brings up a totally awesome idea: Snowboarding down a Martian sand dune on a block of dry ice. » 6/12/13 9:00am 6/12/13 9:00am

Did NASA send the Curiosity Rover to the wrong place?

A new study suggests that Mars’s 3.5-mile high Mount Sharp formed as strong winds carried dust and sand into the crater in which it rests. If true, Gale Crater probably never contained a lake, which would totally suck, because that’s one of the main reasons why NASA sent Curiosity there in the first place. » 5/09/13 9:15am 5/09/13 9:15am

What strange geological processes created Titan's oddly smooth surface?

Saturn's largest moon, Titan, has a surface that doesn't make much sense. Images sent back by the cloud-piercing Cassini-Huygens spacecraft in 2004 showed a smooth surface that was barely touched by its extensive system of liquid methane rivers. And Titan has a strangely small number of impact craters from meteorites. » 7/24/12 11:13am 7/24/12 11:13am
