This image is why everyone's so excited about a NASA mission to Europa

NASA wants to visit Jupiter's moon Europa. Why's that exciting? In a word: Water. As this visualization shows, the icy moon may look tiny next to our own planet, but it's got 2- to 3-times as much H2O as we have here on Earth. That "little" moon is packing quite the store of water — and with it, scientists think, a… » 3/08/14 8:15am 3/08/14 8:15am

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

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

Behold the incredible places where we'll build cities in space

People always forget about radiation when they imagine space colonies. Out there, on other worlds, humans won't be shielded from cosmic radiation the way we are by Earth's magnetic field. That's why cities on other worlds are likely to be underground. Here are few places we might build them. » 7/23/13 1:23pm 7/23/13 1:23pm

The Cities of Europa Glow in Icy Fissures Beneath Jupiter's Swirling…

Flying into Jupiter's moon Europa is always a breathtaking sight. Cities cling to the reflective moon's icy crust, while vast farms swirl in the warm seas below the surface. Now that we've learned to cultivate the native flora and fauna for food, it's become the number one destination in the Jovian system. » 3/22/13 5:36pm 3/22/13 5:36pm

There's more water on Jupiter's moon Europa than there is on Earth

Remember that image from a few weeks back that showed Earth with all its water gathered up in a sphere beside it? Well here's that image again, only this time, it also features Jupiter's moon Europa, along with all of its water. Notice anything interesting? » 5/24/12 1:30pm 5/24/12 1:30pm

What causes Europa's mysterious "chaos terrain"?

Put in plain language, astrophysicists have figured out why Jupiter's moon Europa looks so fucked up. The frozen moon's surface is a layer of solid ice over a liquid sea — and that ice is shattered, cracked, broken, sunken, and twisted into contortions that science can't fully explain. But now a new study suggests one … » 11/16/11 11:00am 11/16/11 11:00am
