Thanks to Hubble telescope's observations as huge geysers erupted from Europa and surged to over 100 miles above its surface, scientists are now certain that Jupiter's icy moon Europa contains water in the form of massive oceans underneath its crust. Continue reading for two videos and more information.
Here's what Dvice has to say: "Hubble originally observed Europa's plumes of water late last year. Scientists looked over the telescope's images and noticed areas that showed an aurora of ultraviolet light. They determined that this light was created by water molecules being broken apart by Jupiter's magnetic field as they shot into the sky. Scientists believe that there are cracks on Europa's icy layer that act as vents for the water vapor. This would be in line with previous observations on Enceladus."
