Roth et al (2014a) reported evidence for plumes of water venting from a southern high latitude region on Europa - spectroscopic detection of off-limb line emission from the dissociation products of water.

The Surface Temperature of Europa

Previous estimates of the surface temperature of Jupiter's moon, Europa, neglected the effect of the eccentricity of Jupiter's orbit around the Sun, the effect of the eclipse of Europa (i.e., the relative time that Europa is within the shadow of Jupiter), and the effect of Europa's internal heating.

The ocean of Jupiter's moon Europa could have the necessary balance of chemical energy for life, even if the moon lacks volcanic hydrothermal activity, finds a new study.

A new NASA study modeling conditions in the ocean of Jupiter's moon Europa suggests that the necessary balance of chemical energy for life could exist there, even if the moon lacks volcanic hydrothermal activity.

Clues to Ocean Composition on Europa

Determining the habitability of Europa's subsurface ocean is one of the key priorities for astrobiology in our Solar System.

We estimate the sensitivity of a lander-based instrument for the passive radio detection of a subsurface ocean beneath the ice shell of Europa, expected to be between 3 km - 30 km thick, using Jupiter's decametric radiation. A passive technique was previously studied for an orbiter.

We present a comprehensive analysis of spatially resolved moderate spectral resolution near infrared spectra obtained with the adaptive optics system at the Keck Observatory.

The outer solar system may provide a potential habitat for extraterrestrial life. Remote sensing data from the Galileo spacecraft suggest that the jovian icy moons, Europa, Ganymede, and possibly Callisto, may harbor liquid water oceans underneath their icy crusts.

Beyond Earth, Jupiter's moon Europa is considered one of the most promising places in the solar system to search for signs of present-day life, and a new NASA mission to explore this potential is moving forward from concept review to development.

When a NASA spacecraft sets off to explore Jupiter's icy moon Europa to look for the ingredients of life, radar equipment designed to pierce the ice of Antarctica will be among the passengers.

NASA has selected nine science instruments for a mission to Jupiter's moon Europa, to investigate whether the mysterious icy moon could harbor conditions suitable for life.

NASA laboratory experiments suggest the dark material coating some geological features of Jupiter's moon Europa is likely sea salt from a subsurface ocean, discolored by exposure to radiation.

Much of the geologic activity preserved on Europa's icy surface has been attributed to tidal deformation, mainly due to Europa's eccentric orbit.

A National Science Foundation (NSF)-funded research team has successfully tested an autonomous underwater vehicle, AUV, that can produce high-resolution, three-dimensional maps of Antarctic sea ice.

NASA Video: Europa: Ocean World

Scientists believe there is an ocean hidden beneath the surface of Jupiter's moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity's most profound questions.

NASA has issued an Announcement of Opportunity (AO) for proposals about science instruments that could be carried aboard a future mission to Jupiter's moon Europa. Selected instruments could address fundamental questions about the icy moon and the search for life beyond Earth.

In November and December 2012 the Hubble Space Telescope maged Europa's ultraviolet emissions in the search for vapor plume activity.

Europa Beckons

In light of today's announcement that Europa is likely spouting its vaporized ocean water into space, The Planetary Society calls on the White House and Congress to approve a new mission to explore this enigmatic moon of Jupiter to better understand its potential to support life.

A new analysis of data from Galileo has revealed clay-type minerals at the surface Europa that appear to have been delivered by a spectacular collision with an asteroid or comet.

Hubble has observed water vapor above the frigid south polar region of Jupiter's moon Europa, providing the first strong evidence of water plumes erupting off the moon's surface.
