Europa

  • 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.

  • 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.

  • Europa: Living World or Frozen Wasteland?
    Within our solar system, Jupiter's moon Europa is on the short list of potentially habitable worlds. It's a bizarre place, believed to contain a globe-spanning ocean covered by a thick layer of ice, and to be pummeled by intense radiation from Jupiter's magnetosphere.

  • Is Europa Corrosive?
    Scientists planning the Jupiter Icy Moon Orbiter met recently to discuss the prospects for finding life on Jupiter's moon, Europa. This icy world however may have enough sulfuric acid mixed in to qualify as a good battery-- but a poor prospect for microbial life as

  • Europa: Frozen Ocean in Motion
    Few places in our solar system can offer more intriguing conditions for primitive life than Jupiter's moon Europa. Covered by a vast ice-sheet, Europa cloaks its subterranean ocean but evidence of a briny, electrically-conductive sea may provide at least two of the conditions needed

  • Europa and Undersea Divers
    From working on Europa research to diving the Atlantic for vent microbes, the SETI Institute's Kevin Hand is getting out there. His handiwork recently was contributed to the exploration voyage of James Cameron, while the Academy Award director hunted for extreme lifeforms.

  • High Tide on Europa
    Cynthia Phillips, an expert on Europa image analysis from SETI Institute, discusses the remarkable way that the Galilean satellites-get their warmth. The moons are heated by eccentric orbits. Called tidal heating, this source of energy has interesting implications for whether liquid water could exist so

  • Fascination with Distant Worlds
    On September 21, the Galileo space probe will dive into the atmosphere of Jupiter. Its trek to the giant planet has revealed stunning images of the Jovian moons, in particular one of its frozen satellites, Europa. Cynthia Phillips of The SETI Institute provides an account

  • Europa Diary IV: Walking on Thin Ice
    The Europa Focus Group, a collaboration of scientists who study Jupiter's ice-covered moon, met recently on Alaska's North Slope. By studying the unique terrain at the edge of the Arctic Ocean, they foreshadow future expeditions to search for life on Europa.
