Huge Saltwater Ocean Found on Jupiter Moon Ganymede
NASA has confirmed that Ganymede, one of the moons orbiting Jupiter, has a saltwater ocean lying below its icy exterior.
The scientists studying the planet and its outlier moons through the Hubble Telescope shared the news in a statement, saying that the ocean may bear more liquid than all the water on Earth combined.
Researchers believe the subterranean ocean is 10 times as deep as Earth’s oceans.
Since water is necessary to sustain life, it's possible these oceans may confirm the long-suspected presence of life on planets, or moons such as Titan and Enceladus.
NASA has speculated since the 1970s that there was water on Ganymede. A 2002 Galileo mission had already confirmed that the moon had its own magnetic field, but the findings weren’t concrete enough to corroborate suspicion that Ganymede had a vast ocean beneath its outer crust—until now.

Well Jupiter's magnetosphere squeezes and streches them constantly wich explains why these satellites get hotter the deeper you go.
Europe is another Jupiter satellite that has an ocean underneath an icy crust, i can't wait our tech is advanced enough so we can send robots into those oceans, i hope i'm alive when that happens.
And Enceladus(not a Jupiter Moon though) is another one that also might have some liquid water.
But yeah i've heard about Ganymede's oceans before I think. It's a lot smaller than Earth though... So how could there be more water? Even if they're 10 times as deep... They're not gonna be 10 times as deep all over...
Haven't they already sent probes past Pluto? If that's the case, then I'm sure they could manage to send some sort of machine to Ganymede to find out more within the next 50 years.
Space has always been so fascinating to me!
