Hot Topic Solar System Jupiter Europa
Europa on Earth
Topic: Europa
Summary: 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
Topic: Europa
Summary: 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
Topic: Europa
Summary: 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
Topic: Europa
Summary: 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.

Europa: Living World or Frozen Wasteland?
Topic: Europa
Summary: 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?
Topic: Europa
Summary: 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 we know it today.

Europa: Frozen Ocean in Motion
Topic: Europa
Summary: 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 for life: liquid water and an energy source.

Europa and Undersea Divers
Topic: Europa
Summary: 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
Topic: Europa
Summary: 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 far from the sun.

Fascination with Distant Worlds
Topic: Europa
Summary: 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 of what further studies might reveal.
