Saturn's rings found to be a young ring newly added to the planet |  Research

A Nasa spacecraft has found that Saturn’s rings have fashioned over the previous few hundred million years – giving weight to the concept that the rings merged way more lately than some scientists thought. This helps an ongoing debate about their age and suggests they aren’t as previous because the planet itself, which is round 4.5 billion years previous.

Saturn has seven rings made up of many items of ice no larger than a rock. They’re very clear as they’re greater than 98% pure water by quantity. Nonetheless, mud from numerous sources in house is understood to maneuver across the photo voltaic system virtually repeatedly, falling on the rings and step by step polluting and darkening the rings over time.

The Cosmic Mud Analyzer on Nasa’s Cassini spacecraft has spent 13 years amassing mud grains from Saturn’s rings. Many of those micrometeoroids have been proven to return from the Kuiper Belt, the doughnut-shaped ring of ice and dirt that surrounds the photo voltaic system. Primarily based on the gathering of mud grains, the scientists concerned within the examine had been in a position to calculate a mud movement charge for Saturn’s rings.

Utilizing this movement charge and the quantity of collected mud, which is estimated to be solely 0.1-2% of the rings by quantity, the researchers conclude that Saturn’s rings have been forming for lower than 400 million years. Whereas rings are a latest characteristic of the Saturn system, questions nonetheless stay as to how they fashioned within the first place and whether or not they’re a brief characteristic on planetary timescales.
