Jupiter's Moon Europa Shoots Water Into Space, New Research Suggests

Jupiter's Moon Europa Shoots Water Into Space, New Research Suggests Jupiter's Moon Europa Shoots Water Into Space, New Research Suggests

Europa has always been thought to cover a salty ocean about twice the size of our planet's.

Rather than forming a mission to land on Europa, drill down to where the liquid water hides, and then take samples from there, NASA now hopes that a probe flying through the water plumes could grab some of the material, run tests, and report its findings.

In a paper in the journal Nature Astronomy Jia describes how his team build custom 3D modelling code to work out a plume's density and properties, adding in the magnetic data from the Enceladus plume probe.

"To detect a plume for certain, we'll have to return to the Jupiter system, and NASA's Europa Clipper spacecraft, now in development, will do just that", Cynthia Phillips, a NASA researcher told Mashable. Jia and his team took an in-depth look at information the probe gathered during the closest of these encounters - a 1997 flyby that brought Galileo within 128 miles (206 km) of the moon's frigid, fractured surface. They believe that this may also point to evidence of life on the moon.

The spacecraft, launched in 1989 to examine the fifth planet from the Sun with its dozens of moons, became the first in 1995 to enter the orbit of a gas giant planet.

Ironically Galileo ended its mission by plunging into Jupiter's atmosphere in September, 2003 to prevent an unwanted impact with Europa, but the legacy of its treasure-trove of data clearly still lives on.

At 1,900 miles (3,100 kilometers) wide, Europa is slightly smaller than Earth's moon.

Researchers believe that Europa contains a global salt water ocean under its crust. If NASA (and the rest of us who care about the search for alien life) get lucky, those jets may be on when the Europa Clipper reaches its destination and starts its science work.

Europa is one of the most talked-about bodies in the Solar System, not only because it was so integral to Arthur C Clarke's classic 2001 series, and the new data is already being put into action.

"These results provide strong independent evidence of the presence of plumes at Europa", they wrote. To study the makeup of the water on Europa, scientists would only need to perform flybys with spacecraft going through the plumes instead of landing on the moon.

Recently, evidence has been building that Europa may have a plume as well.

That region was in an area where the Hubble Space Telescope had spotted repeated evidence of plumes.

The conditions could serve as a stand-in to investigating alien life, scientists say. Some have suggested that there might be a subsurface lake hiding between layers of Europa's thick ice sheets.

If it finds a plume, Clipper's instruments will be able measure its chemical composition, said Elizabeth Turtle, a planetary scientist at the Johns Hopkins Applied Physics Laboratory and one of the primary researchers involved with the mission.

'If we can collect a sample of the water, we may determine whether microbial life exists, how it evolved, and how it continues to live in this cold environment with no connection to the atmosphere'.
