Geysers on Saturn's moon Enceladus

Référence de la vidéo 12329654
Animation of Saturn's moon Enceladus passing in front of the planet, showing water ice geysers erupting from its south pole. Enceladus is an icy inner moon of Saturn, orbiting some 180, 000 kilometres above its cloud tops, within the giant planet's E ring. The geysers that erupt from its south pole are the source of the material making up this ring. The geysers are powered by the hot core of the small moon, with the heating thought to be due to it being locked in an 1:2 orbital resonance with the more distant moon Dione, with the resonance deforming the moon's rock and ice over the course of its orbit, producing frictional heating. It is thought that there is an ocean of liquid water beneath the ice, and taken together with the geothermal activity, Enceladus' ocean is a prime target for missions searching for extraterrestrial life. Detection of molecular hydrogen in the geyser plumes is a strong indication that the required conditions for habitability are met.
