Europe could rise by spray from the ocean hidden beneath its surface. They could lead traces of the presence of life forms.

Astronomers, oceanographers and fans are wondering for years what it may contain extraterrestrial oceans, such as the one that you think is hidden under the icy crust of Europa, one of Jupiter‘s moons.

Penetrate the casing would be very difficult, but if traces of that water were “fired” in space, maybe we could send a probe to analyze them. Why were greeted with hope the results of a new series of observations made by the Hubble telescope: it seems that Europe rise up plumes of water vapor coming from that very mysterious inner ocean. Doubt is still a must, because the astronomers point out that the comments have not yet incontrovertible proof of those plumes. “In a couple of cases we see structures that could be plumes, but do not consider the evidence,” says William Sparks of the Space Telescope Science Institute. “It is very difficult observations, at the limit of Hubble’s capabilities.” But, given that NASA is going to send a mission to explore Europa, the results are promising. “They are definitive proof? No. I’m promising? A lot. It is useful to send a mission to Europe to learn more of this small, beautiful moon with an ocean? Absolutely,” says Kevin Hand from NASA, another member of the team He has described the new findings in an article in the Astrophysical Journal. The ocean of Europe is considered one of the places where suitable to the presence of extraterrestrial life, but because it is hidden under a thick ice sheet several kilometers, reach it is practically impossible.

But if indeed the satellite “spit” water vapor, a probe could collect samples and analyze them to see if that subterranean sea is suitable for supporting life. And this is precisely the objective of Europe Clipper mission, which NASA plans to launch in the next decade.
