NASA is making announcements on some unbelievable results of the observation campaign of Europa, i.e. Jupiter's moon. During a press conference, the representatives of NASA are briefing whatever they discovered. Media conference is still going on.
Read on to find the details. And stay tuned for more updates.

A comparison of 2014 transit and 2012 Europa aurora observations. The raw transit image, left, has dark fingers or patches of possible absorption in the same place that a different team (led by Lorenz Roth) found auroral emission from hydrogen and oxygen, the dissociation products of water.
Artist's concept: Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. If the plumes, indeed, emerge and rain down on the surface, it may be much easier to access material that was once in the ocean of Europa.
Europa transit illustration. Europa orbits Jupiter every 3 and a half days, and on every orbit it passes in front of Jupiter, raising the possibility of plumes being seen as silhouettes absorbing the background light of Jupiter.

That's incredible, as it is confirmed by NASA.

So, NASA has confirmed that Europa has the presence of water, and it is fantastic.
