This is a high-gain antenna (HGA) and a future version of it will send and receive signals to and from Earth from a looping orbit around Jupiter.

Europa's Optical Aurora

Auroral emissions provide opportunities to study the tenuous atmospheres of Solar System satellites, revealing the presence and abundance of molecular and atomic species as well as their spatial and temporal variability.

Spacecraft landing on Jupiter's moon Europa could see the craft sink due to high surface porosity, research by Planetary Science Institute Senior Scientist Robert Nelson shows.

Possible Plate Tectonics on Europa

A Brown University study provides new evidence that the icy shell of Jupiter's moon Europa may have plate tectonics similar to those on Earth.

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other "ocean worlds" in our solar system and beyond.

A mission to examine the habitability of Jupiter's ocean-bearing moon Europa is taking one step closer to the launchpad, with the recent completion of a major NASA review.

A report on the potential science value of a lander on the surface of Jupiter's icy moon Europa has been delivered to NASA, and the agency is now engaging the broader science community to open a discussion about its findings.

Evidence of Water Vapor Plumes on Europa

Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes.

Jupiter's moon Europa is under a constant gravitational assault. As it orbits, Europa's icy surface heaves and falls with the pull of Jupiter's gravity, creating enough heat, scientists think, to support a global ocean beneath the moon's solid shell.

Probing the Mysteries of Europa

Jupiter's moon Europa is believed to possess a large salty ocean beneath its icy exterior, and that ocean, scientists say, has the potential to harbor life.

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.

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.

Stunning Remastered View of Europa

Scientists have produced a new version of what is perhaps NASA's best view of Jupiter's ice-covered moon, Europa.

NASA has chosen proposals from 10 universities to study CubeSat concepts that could enhance a Europa mission concept currently under study by NASA.

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.

Reddish Bands on Europa

This colorized image of Jupiter's moon Europa is a product of clear-filter grayscale data from one orbit of NASA's Galileo spacecraft, combined with lower-resolution color data taken on a different orbit.

Where is the best place to find living life beyond Earth? It may be a small, ice-covered moon of Jupiter or Saturn that harbors some of the most habitable real estate in our Solar System.

Recreating the Crust of Europa

Scientists suspect that inside Europa, one of the icy moons of Jupiter, reservoirs of liquid water exist, the essential element for life on Earth.

This reprojection of the official USGS basemap of Jupiter's moon Europa is centered at the estimated source region for potential water vapor plumes that might have been detected using the Hubble Space Telescope.
