Nov 5, 2021 · NASA’s Hubble Space Telescope has found the best evidence yet for an underground saltwater ocean on Ganymede. The ocean is thought to have more water than all the water on Earth's surface.

Nov 5, 2021 · Jupiter’s icy moon Ganymede is the largest moon in our solar system, even bigger than the planet Mercury, and the dwarf planet Pluto. There’s strong evidence that Ganymede has an underground saltwater ocean that may hold more water than all the water on Earth's surface.

Mar 13, 2015 · A salty ocean is lurking beneath the surface of Jupiter's largest moon, Ganymede, scientists using the Hubble Space Telescope have found.

Mar 12, 2015 · NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water on Earth’s surface.

Feb 3, 2015 · We present a new approach to search for a subsurface ocean within Ganymede through observations and modeling of the dynamics of its auroral ovals. The locations of the auroral ovals oscillate due to Jupiter's time-varying magnetospheric field …

Mar 12, 2015 · NASA held a press briefing today to discuss a newly published paper that confirms a subsurface ocean at Ganymede. The idea that Ganymede has a global layer of liquid water is not a new one. Margaret Kivelson and coworkers described evidence for it from Galileo magnetometer data in 2002.

May 6, 2023 · Ganymede is Jupiter's largest moon and is also the largest moon in the entire solar system. It is bigger than both Mercury and dwarf planet Pluto and only slightly smaller than Mars. The...

Mar 12, 2015 · In recent years, scientists have found evidence for liquid oceans trapped under the ice of Jupiter’s moon Europa and Saturn’s moon Enceladus. And today, Hubble Space Telescope researchers announced...

Dec 16, 2000 · A thick layer of melted, salty water somewhere beneath Ganymede's icy crust would be the best way to explain some of the magnetic readings taken by NASA's Galileo spacecraft during close approaches to Ganymede in May …

May 1, 2014 · In the 1990s, NASA's Galileo mission flew by Ganymede, confirming the moon's ocean, and showing it extends to depths of hundreds of miles. The spacecraft also found evidence for salty seas, likely containing the salt magnesium sulfate.
