Saturn's moon Titan could have formed in a merger of two old moons

Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of Saturn, the discoveries ...

Tiny Enceladus exercises giant electromagnetic influence at Saturn

A major study by an international team of researchers using data from the NASA/ESA/ASI Cassini spacecraft has revealed a lattice-like structure of crisscrossing reflected waves that flow downstream behind the moon in Saturn's ...

Polar weather on Jupiter and Saturn hints at the planets' interior details

Over the years, passing spacecraft have observed mystifying weather patterns at the poles of Jupiter and Saturn. The two planets host very different types of polar vortices, which are huge atmospheric whirlpools that rotate ...

Experiments bring Enceladus' subsurface ocean into the lab

Through new experiments, researchers in Japan and Germany have recreated the chemical conditions found in the subsurface ocean of Saturn's moon, Enceladus. Published in Icarus, the results show that these conditions can readily ...

Astronomers measure both mass and distance of a rogue planet for the first time

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets seem to have been knocked out of their orbits, floating through space free of any particular gravitational ...

Saturn's icy moon Enceladus is an attractive target in the search for life—new research

A small, icy moon of Saturn called Enceladus is one of the prime targets in the search for life elsewhere in the solar system. A new study strengthens the case for Enceladus being a habitable world.

Saturn's rings extend further above and below the ring plane, forming a 'halo'

The Cassini probe took its final orbits, referred to as the Grand Finale Orbits (GFOs), in 2017, before launching itself into Saturn's atmosphere. During these GFOs, the probe collected samples of dust above and below Saturn's ...

Saturn's biggest moon might not have an ocean after all

Careful reanalysis of data from more than a decade ago indicates that Saturn's biggest moon, Titan, does not have a vast ocean beneath its icy surface, as suggested previously. Instead, a journey below the frozen exterior ...
