Europa

  • Waves Crash on Europa
    New studies indicate that Europa may harbor a more dynamic ocean than previously believed beneath its icy exterior. The gravitational pull of Jupiter could be producing powerful waves in the ocean, which in turn could have implications on the habitability of the unique moon.

  • Unmasking Europa
    We may not be able to judge a book by its cover, but hopefully we can judge a moon by its surface. A scientist who worked on the Galileo mission has written a new book about the scratched and splotchy surface of Europa.

  • Exploring Europa on Earth
    An ocean lies beneath the icy crust of Jupiter´s giant moon Europa. At the bottom of that ocean, there could be hydrothermal vents that provide all of the ingredients needed to support life.

  • Hoping for Europa
    NASA and ESA are now deciding on the next major mission to the outer solar system. One proposal is to visit two of Jupiter´s large moons, Ganymede and Europa. Astrobiologists have long hoped to study Europa more closely because its global ocean could harbor

  • Mini-Sub for Small Spaces
    New from the Nordic issue of Astrobiology Magazine, European Edition is a story about a tiny submarine. Swedish researchers are developing a remote-controlled submersible that can fit through drilled holes in thick ice caps.

  • Cracking the Question of Alien Life
    New research is providing clues about the potential for life on Europa. By studying Europa's surface, scientists hope to determine the best places to search for life and whether or not the moon is geologically active.

  • Europa’s Wandering Poles
    Features on Jupiter's moon Europa indicate that its poles may have wandered by as much as 90 degrees. This extreme shift supports the theory that Europa harbors a liquid ocean beneath its icy crust.

  • 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

  • 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

  • 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.
