PIX4575163: Jupiter from its satellite Europe - Illustration - Jupiter from Europa - Illustration - Europe, Jupiter's second largest satellite, could house an ocean of liquid water beneath its icy surface. Europa, the second large moon of Jupiter, is thought to have an ocean of liquid water beneath a crust of ice. Tidal stresses from Jupiter and its neighboring moons might sometimes split open this crust, briefly exposing the liquid water to the vacuum of space, Bergeron, Joe / Bridgeman Images
PIX4625762: Under the rings of Saturn - Saturn Atmosphere Probe - Artwork - A space probe descends through the clouds of Saturn. A halo is visible around the Sun. To see the Saturn rings this open, you would have to be far north or south of the planet's equator. They are backlit, and so look a little peculiar. A probe has been added to provide a visual focal point, Bergeron, Joe / Bridgeman Images
PIX4625857: Geyser sur Enceladus - Artist view - Water geyser on Enceladus - Artist view - Artist view of an ice geyser on the surface of the Enceladus satellite. In the sky, the planet Saturn. A look at the water geysers of Saturn's moon Enceladus, which have been revealed to us so brilliantly by the Cassini Saturn orbiter. This digital illustration shows the water jets shooting out from vents in the bottom of one of the icy moon's multitude of folded, fractured valleys, Bergeron, Joe / Bridgeman Images
