Jupiter's Moon Ganymede Has a Salty Ocean With More Water Than Earth

A salty ocean is lurking beneath the surface of Jupiter's largest moon, Ganymede, scientists using the Hubble Space Telescope have found. According to NASA officials, the ocean on Ganymede — which is buried under a thick crust of ice — could actually harbor more water than all of Earth's surface water combined. NASA added, Scientists think the ocean is about 60 miles thick, 10 times the depth of Earth's oceans. The new Hubble Space Telescope finding could also help scientists learn more about the plethora of potentially watery worlds that exist in the solar system and beyond.
