Saturn’s rings, imaged here by NASA’s Cassini orbiter, are one of the solar system’s most reliably spectacular sights. But ...

A new study implies that in the past, moons in our solar system may have had rings just like planets do — deepening the ...

But later – hundreds of millions of years in the future – a permanent, virtually ringless Saturn will become real, thanks to another process called ring rain in which gravity pulls the rings apart and ...

Our Solar System is a carefully balanced celestial dance held together by a virtually perfect balance of gravity and inertia.

Although the other giant planets in the Solar System have rings, too, they are nothing like Saturn's. Jupiter, Uranus, and Neptune are all banded by dainty, ethereal rings that can hardly be seen ...

This, actually, is weird. Of the eight planets in the Solar System, half have rings of dust and ice orbiting their equator. Mars is thought to have once had a ring. Some of the dwarf planets have ...

The so-called 'planetesimal belts' are filled with tiny millimeter-sized particles created by collisions between comets.

It may seem like Earth isn't as well-decorated as its ring-bearing neighbors in the solar system, but new research suggests ...

When you first learned about the Solar System, you probably saw diagrams that made it look orderly, with planets arranged in ...

(NASA/JPL/Space Science Institute) Saturn, by contrast, is practically defined by its extensive rings. It seems likely that, outside the Solar System, rings could be common, given the large number ...
