Hubble Sees Water Venting from Jupiter’s Moon Europa

Made famous in the movie 2001 a Space Odyssey Jupiter’s Moon Europa may make truth out of the science fiction movie. We have not heard the message from the movie telling us to “make no landings there” but Hubble has found water venting into space. Jupiter is five times farther from the Sun than Earth, and so cold that ice becomes as hard as rock. The surface is definitely not a place we would see water but inner the surface where the gravitational forces of Jupiter pull and stretch the moon liquid water cold exist. Jupiter’s moon Europa may be the first place to go to look for extraterrestrial life. Ever since the moon, which superficially resembles a cracked eggshell, was photographed close-up by the Voyager space probe, scientists have been intrigued by its potential as a niche for life.

For over the past 30 years it has been hypothesized that the icy crust covers a subsurface ocean. Where there is water there could be life. Now NASA’s Hubble Space Telescope has found something the Jovian probes may have missed, plumes of water vapor leaking off into space near the moon’s south pole. Astronomers do not know yet if these gas plumes are connected to subsurface liquid water or not. This venting doesn’t seem unique. In 2005, NASA’s Cassini orbiter discovered similar water vapor plumes spewing off of the tiny moon Enceladus, 1 billion miles away.
