Return to Europa
Many scientists are now convinced that Jupiter's moon Europa harbors a liquid ocean beneath its icy crust. The main question now is, could this ocean support life as we know it?

Swimming a Salty Sea
If there is life on Jupiter’s moon Europa, what would it be like? The answer partly depends on the type of ocean water that is under the moon's icy outer shell.

Fixing the Photo Flash
New imaging detectors that can withstand the harsh radiation of space could be used to confirm the presence of lakes or oceans on Jupiter's moon Europa. If Europa does harbor an ocean beneath its icy crust, the moon might be one of the best places to look for life in our Solar System.

DEPTHX Diving
NASA is preparing an underwater robot for a plunge into Earth's deepest sinkhole. The mission will be used to map the Zacatón sinkhole, and also to develop technologies that could be used to explore below the icy crust of Europa.

Targeting Europa
Jupiter's moon Europa could harbor a subsurface ocean and maybe even life, so some researchers feel it should be a primary target of NASA's next 'flagship' mission to the outer solar system.

The Road to Europa
Scientists are currently discussing the benefits of studying each of Jupiter's four large moons with a dedicated mission. In a recent talk to the American Geophysical Union, the case was made for visiting Europa in order to learn more about the moon's ocean and possibly the origins of life.

Europa on Earth
This summer, a science team set out on a two-week expedition of Earth's own little version of Jupiter's moon Europa -- the Borup Fiord Pass at Ellesmere Island, a place hidden high above the rest of the world in the Canadian High Arctic.

Hitting Europa Hard
Europa remains a tantalizing target for astrobiologists –- but what would be the best way to investigate the mysterious moon? In this interview, Karl Hibbitts describes a proposed hyper-velocity impactor that would smack right into Europa’s outer ice shell.

Blonde Europa
Some may be surprised to learn that bleach-blondes and the enabler of life elsewhere in our solar system have something in common. And, no, it's not intelligence. It is, in fact, hydrogen peroxide.

The Lure of Europa
Jupiter's moon Europa is thought to be one of the most likely abodes for microscopic life in our solar system. The discovery that Europa most likely has a cold, salty ocean beneath its frozen icy crust has put Europa on the short list of objects in our solar system that astrobiologists would like to study further.
