NASA confirms water vapour from Europa (science news).

Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa the look of a veiny eyeball. Missions to the outer solar system in the decades since have amassed enough additional information about Europa to make […]

Life on Europa? Chances tick up with new evidence in Europa’s plumes.

Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell. Data collected by NASA’s Galileo spacecraft in […]

Water plumes ahoy, erupting from Jupiter’s moon, 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. The observation increases the possibility that missions to Europa may be able to sample Europa’s ocean […]

Europa’s sea-life? Just became likely with NASA’s salt ocean findings.

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. The presence of sea salt on Europa’s surface suggests the ocean is interacting with its rocky seafloor — an important consideration in determining whether the icy moon […]
