Young Jupiter’s powerful magnetic field may have created a safe zone where several large moons could survive. Saturn lacked this protection, possibly explaining why Titan stands almost alone among its ...

A new study published in Nature Astronomy proposes an explanation for a long-standing puzzle in planetary science: why Jupiter ended up with four large moons while Saturn has only one comparably ...

A model based on numerical simulations reveals why Jupiter has a larger number of larger moons than Saturn. The model, developed by a team of astronomers from Japan and China, has also uncovered how ...

We've been treated to some crystal clear nights over the past few weeks, and Jupiter has been standing out like a shining beacon high above Big Sky.

NASA's Juno spacecraft has snuck a peek at one of Jupiter's largest inner moons. During a close flyby, the spacecraft got a look at Jupiter's moon Thebe from just 3,100 miles (5,000 kilometers) away.

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a ...
