Details of Saturn's icy rings are visible in this sweeping view from Cassini of the planet's glorious ring system. The total span, from A ring to F ring, covers approximately 40,800 miles (65,700 ...

That puts its rings at a distance of roughly 7.4 of the dwarf planet’s radii from its core—twice as far as the maximum distance, called a “Roche limit,” astronomers previously thought ...

Based on the width of the lane it’s cleared between rings, one of those moons may be at least the size of Earth. If J1407b really is a rogue planet, at least it’s not completely alone out there.

What a planet's ring is made of also partly depends on where it is. In the outer solar system, it's cold enough for ice to form. But "if Earth had a ring, it wouldn't be made of ice because Earth ...

CAPE CANAVERAL, Fla. — New research suggests that Saturn’s rings may be older than they look — possibly as old as the planet. Instead of being a youthful 400 million years old as commonly ...

Astronomers had long assumed that Saturn's distinctive rings formed around the same time as the planet some 4.5 billion years ago in the earliest days of our Solar System.
