NASA shares the moon’s exact distance from Earth and its impact on ocean tides, solar eclipses, and space travel. See how this celestial dance shapes our world.

One of Uranus’ moons, Miranda, could have a liquid ocean beneath its icy surface that might even harbor extraterrestrial life. If so, this would place Miranda among the few worlds in our solar ...

A surprisingly youthful ocean within Mimas, a tiny moon of Saturn, ... an 80-mile-long pit with a prominent central peak that gives the lumpy moon its Death Star aesthetic.

Data from India's recent Chandrayaan-3 mission supports the idea that an ocean of molten rock once covered the moon.

A subsurface sea on Saturn’s moon Enceladus spews plumes of water vapor into space. And there are tantalizing hints that oceans could exist on Ganymede, Callisto, Titan and other distant moons, too.

Scientists have found that one of Saturn's moons might be harboring an ocean of water beneath its icy surface. Mimas, which is Saturn's 7th largest moon and resembles the Death Star from Star Wars ...

This would have meant the newly formed moon was covered entirely in magma: a global magma ocean, so hot and deep that it took at least tens of millions of years to cool and solidify into rock.

The ocean is believed to fill half of Mimas’ volume, according to Lainey. Yet it represents only 1.2 percent to 1.4 percent of Earth’s oceans given the moon’s petite size.
