NASA released this amazing image of Enceladus, the frozen moon of the planet Saturn, earlier today. This image was taken by NASA’s Cassini spacecraft, which has been orbiting Saturn since 2004 and which has performed 33 flybys to date of this moon. The stripe in the background is Saturn’s rings. Cassini was the first to image ice volcanoes on Enceladus. It was also the first to analyze the geyser-like plumes of icy water and ammonia scattered on its surface.
It’s thought that tidal heating from its lopsided orbit of Saturn warms the center of Enceladus enough to cause it to have oceans of liquid water deep beneath a shell of ice several to hundreds of kilometers deep. Only further exploration will settle the question of liquid water on Enceladus.
