Earth has one moon whereas Jupiter has 79 know moons, among them one of the moons is Europa. Europa or Jupiter ll was discovered by Galileo Galilei in 1610. This Europa is made of water and has a very thin atmosphere. Hubble space telescope detected water vapour plumes similar to those observed on Saturn’s moon
Though Jupiter is so far from the sun and the temperature of Europa is -160 to-220 degree Celsius the Presence of water in Europa is surprising... Europa orbits Jupiter in oval shape and takes 3.5days to complete one revaluation. When Europa comes close to Jupiter it gets expanded due to the gravitation of Jupiter. Then it contracts while far away from Jupiter which produces heat in Europa. This is the process of heat development is called tidal flexing. So it contains water in its undersurface. The above surface contains float ice 15 to 25 km upside. Scientist predicting there must be the presence of water animals like aliens.
The presence of water in Europa is 2times the presence of water on Earth. Europa contains oxygen due to radiation from Jupiter it formed. Anyways there is no possibility for a human to live. Because the presence of oxygen us trace amount and radiation from Jupiter affect humans.
