Scientists find out that Saturn’s rings are new to the universe.
Scientists have found that Saturn’s famous rings are only 400 million years old. This means that the rings are much younger than the planet itself, which means that Saturn didn’t have any rings in the past.
New study shows that these rings are much younger than was thought before. They are less than a tenth as old as the planet.
This seems to solve a long-standing problem in astronomy, and a group of US experts found the answers in the dust.
Professor Sascha Kempf, who led the study, says that if you think of Saturn’s rings as the rugs in your house, it will be easier to understand what they found.
“If you’ve put out a clean carpet, all you have to do is wait. Your carpet will get dirty. “The same goes for the rings,” said Kempf.
The famous rings of Saturn have finally been given a date.
There have been many ideas about how these rings came to be. Some people said they formed on their own, while others said they were probably made not too long ago by the debris of an unstable moon that burst or the ice, rocks, and dust left by a passing comet that may have hit the satellite.
The team from the University of Colorado Boulder says that Saturn’s rings are “no more than 400 million years old.”
“That makes the rings much younger than Saturn itself, which is about 4.5 billion years old,” Professor Kempf said. “In a way, we have an answer to a question that started with James Clerk Maxwell.”
Maxwell, a famous Scottish scientist, was the first person to think that Saturn’s rings must be made up of many small pieces. The gap in Saturn’s C ring that is called the Maxwell Gap is named after him.
Almost every day, rocks and broken planets from space rain down on Earth. This change can sometimes leave a thin layer of dust on planets.
Professor Kempf and her students looked at how quickly this layer builds up.
Between 2004 and 2017, this group of scientists used the Cosmic Dust Analyzer, a high-tech tool on NASA’s Cassini probe, to study dust particles in orbit.
“Over those 13 years, the researchers found only 163 grains that came from outside the planet’s close neighborhood,” the study said, adding that this was enough to strongly suggest that the dust on the rings had only been there for a few hundred million years.
This is sometimes a very short-lived event.
“We have an idea of how old the rings are, but that doesn’t help us solve any other questions. Professor Kempf said, “We still don’t know how these rings formed in the first place.”
