Planet rings could be behind the formation of solar system satellites Date: December 4, 2012 Source: Commissariat a l'Energie Atomique (CEA) Summary: Two researchers have recently proposed the ...

This Aug. 22, 2009 image made available by NASA shows a section of Saturn's rings, as seen from the Cassini spacecraft. The icy, shimmering rings could be around 4.5 billion years old just like ...

What are the rings around planets made of? — Vihan, aged five, Chennai, India Lots of us are familiar with pictures of the planet Saturn and its unmistakable ring.

A planet’s moons can also influence its ring system. For example, Jupiter has rings just like the other gas giants, but its rings are smaller and fainter than Saturn's. Jupiter's multiple large ...

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 ...

Scientists say that Saturn's rings are falling in on the planet as icy rain due to the gas giant's intense gravity. Saturn's rings are made of pieces of comets, asteroids or moons.

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 ...

Skipping over Saturn, we come to Uranus, which has 13 rings, though they’re pretty dark. The planet is seen from Earth as a green orb, with the rings pretty much invisible.

Saturn, its rings and its moons will be paying a "close" visit to Earth Tuesday night. Saturn is at "opposition" that day, meaning the planet and the sun are on opposite sides of the Earth ...

Instead of being a youthful 400 million years old as commonly thought, the icy, shimmering rings could be around 4.5 billion years old just like Saturn, a Japanese-led team reported Monday.

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.

New research has cast doubt on the long-held belief that Saturn's rings are relatively young, suggesting instead that they could date back 4.5 billion years to when the planet formed. The study ...
