New research emerging from the final orbits of NASA’s Cassini spacecraft represents a huge leap forward in our understanding of the Saturn system — especially the mysterious, never-before-explored ...

New data from NASA’s Cassini spacecraft reveals that Saturn’s iconic rings extend far beyond the thin plane we’ve long observed through telescopes. During its final orbits in 2017, Cassini discovered ...

The size of Uranus' rings is controlled by the planet's five major moons, which are able to eject significant amounts of dust out of the Uranian system, according to new simulations designed to figure ...

Cassini spacecraft image of shepherd moons Pandora and Prometheus (each roughly 80 kilometers in diameter) acting on Saturn’s F ring. The satellites’ gravity causes the perturbations shown here, which ...

A thrilling ride is about to begin for NASA’s Cassini spacecraft. Engineers have been pumping up the spacecraft’s orbit around Saturn this year to increase its tilt with respect to the planet’s ...

All four of the solar system’s giant planets have ring systems. The rings of Jupiter, Uranus, and Neptune are dark, sparse belts or ringlets. Only Saturn’s massive main rings are dense and bright, ...

Listen, we know this has already been a disorientating year so far, but Saturn is about to lose its iconic rings. Well, sort ...

Specks of dust from Saturn’s rings appear to float much farther above and below the planet than scientists thought possible, suggesting the rings are more like a giant dusty doughnut. The main ...
