Could a liquid water ocean beneath the surface of Jupiter's moon Europa have the ingredients to support life? Here's how NASA's mission to Europa would find out.

Europa mission news conference.
NASA announced on Tuesday, May 26, 2015, the selection of science instruments for a mission to Europa, to investigate whether Jupiter's icy moon could harbour conditions suitable for life.
Jupiter's moon Europa is brimming with water. Although it is thought to be mostly made up of rocky material, the moon is wrapped in a thick layer of water - some frozen to form an icy crust, some potentially pooled in shallow underground lakes or layers of slush, and vast quantities more lurking even deeper still in the form of a giant subsurface ocean.
With the first detailed observations of a lava lake on a moon of Jupiter, the Large Binocular Telescope Observatory in Arizona places itself as the forerunner of the next generation of Extremely Large Telescopes.
On Earth, bursts of particles spewed by the Sun spark shimmering auroras, like the Northern Lights, that briefly dance at our planet's poles.
NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon.
Firing off a string of action snapshots like a sports photographer at a NASCAR race, NASA's Hubble Space Telescope captured the rare occurrence of three of Jupiter's largest moons racing across the banded face of the gas-giant planet: Europa, Callisto, and Io.
Four bleary-eyed men wearing grease-smeared tan jackets or red parkas emerge from what first appears to be a leftover prop from a Mad Max film. Nine silver smokestacks tower above nine fire-engine-red hot water tanks, all bolted down to a large sled.
The new research provides a snapshot of Europa's state of activity at that time, and suggests that if there is plume activity, it is likely intermittent.
The ruddy color of Jupiter's Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet's upper atmosphere, according to a new analysis of data from NASA's Cassini mission.
Hubble treats astronomers to gorgeous close-up views of the eerie outer planets. But it's a bit of a trick when it seems like the planet's looking back at you!
Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth.
Three massive volcanic eruptions occurred on Jupiter's moon Io within a two-week period last August, leading astronomers to speculate that these presumed rare "outbursts".
Jupiter's trademark Great Red Spot -- a swirling anti-cyclonic storm larger than Earth -- has shrunk to its smallest size ever measured.
When NASA's Juno spacecraft flew past Earth on Oct. 9, 2013, it received a boost in speed of more than 8,800 mph (about 7.3 kilometer per second)
On Dec. 4, 1973, NASA's Pioneer 10 spacecraft sent back images of Jupiter of ever-increasing size.
Recent work by planetary scientists has indicated that the deep atmospheres of Jupiter and Saturn may contain chunks of diamond floating in a liquid hydrogen/helium fluid.
NASA's Juno spacecraft launched aboard an Atlas V rocket from Cape Canaveral Air Force Station, Fla., Aug. 5, 2011, beginning a five-year journey to Jupiter. But it wasn't charted on a direct path. Before it reaches its destination, Juno will greet the Earth one last time. The spacecraft will perform a flyby Oct. 9, passing within 347 miles of Earth.
