Video - Alien Ocean: NASA’s Mission to Europa.

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.

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.


Europa - Chaos on a Watery World

Europa - Chaos on a Watery World

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.

On Earth, bursts of particles spewed by the Sun spark shimmering auroras, like the Northern Lights, that briefly dance at our planet's poles.


Possible Underground Ocean on Jupiter's Moon Ganymede

NASA's Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter's largest moon.


Hubble Views Jupiter and Its Moon Shadows

Hubble Views Jupiter and Its Moon Shadows Video in Story

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.


Using Antarctica to Prepare for Europa Mission

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.


Signs of Europa Plumes Remain Elusive in Search of Cassini Data

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 Origin Of Jupiter's Great Red Spot

The Origin Of Jupiter's Great Red Spot

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!


Evidence of 'Diving' Tectonic Plates on Jupiter's Moon Europa

Evidence of 'Diving' Tectonic Plates on Jupiter's Moon Europa

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.


Massive Eruptions on Io

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".

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)


Forty Years Ago, Pioneer 10's Closest Approach to Jupiter

On Dec. 4, 1973, NASA's Pioneer 10 spacecraft sent back images of Jupiter of ever-increasing size.
