There's something going on beneath the surface of Jupiter's icy moon Europa. But what?NASA teased a "surprising" announcement for Monday, based on Hubble Space Telescope images of the celestial body, which many experts believe could contain a subsurface ocean, even possibly some form of life. <br />The US space agency has already proclaimed that Europa has "strong evidence for an ocean of liquid water beneath its crust and which could host conditions favorable for life." <br />At Monday's announcement, "astronomers will present results from a unique Europa observing campaign that resulted in surprising evidence of activity that may be related to the presence of a subsurface ocean," it said in a statement. <br />The announcement will be made at a news conference at 2 pm (1800 GMT) Monday featuring Paul Hertz, NASA's director of astrophysics, and William Sparks, an astronomer with the Space Telescope Science Institute in Baltimore. <br /> <br /> <br />Don't forget, support this game as it's completely free and you can get it here: <br />http://en.spaceengine.org
