NASA's Voyager probes passed through Jupiter's system and snapped pictures of its largest moons, also known as the Galilean moons. These pictures and the data they gathered offered the first hints ...

New findings from China's Chang'e 6 lunar farside samples offer insights into the moon's volcanic past and mantle evolution.

Callisto, the second-largest moon of Jupiter, is covered in craters and appears, at first glance, geologically inactive. However, magnetic measurements taken by the Galileo probe in the 1990s suggest ...

The first study on the Moon samples brought back by the Chinese Chang'e-6 mission show that the Moon's far side was just as molten as the near one eons ago.

Space Is Callisto, Jupiter’s moon with the most craters and third largest in the Solar System, an oceanic world with life? Callisto, the outermost of the 95 Jovian moons, first caught NASA’s ...

This discovery is exciting because if Callisto has a vast ocean, it could potentially support some form of life, just like other ocean worlds such as Europa and Saturn’s moon Enceladus.

Confirmation of Callisto's status as an ocean world would likely prompt further investigation into its potential to support life—just as the confirmation inspired research into Europa.

Using computer models, researchers studying Pluto and its moon, Charon, have discovered an unforeseen kind of cosmic collision and the potential for oceans in the outer solar system.

Volcanic activity on Io -- the innermost Galilean moon of Jupiter and the most volcanically active body in the Solar System -- is unlikely to be sourced from a global magma ocean just below the ...

Io does not have a shallow global magma ocean beneath its surface, counter to previous claims, suggests a paper published in Nature.
