Saturn did not immediately have rings that would soon disappear

Dinosaurs on Earth appeared and die before the publication of the ring in Saturn / NASA / JPL-Caltech / Institute of Space Science [19659004] Scientists discovered The famous Saturn rings are considerably younger than before, they appeared around the planet about 10 million years ago

Thus, even Saturn itself is older than most of its peculiarities After all, the planet is 4.2 billion years old, she writes Newsweek It turns out that the rings were formed only around Saturn and, meanwhile, the dinosaurs have already appeared and are dying from Earth, which eventually disappeared about 65 million years ago.

These rings remain mysterious. They are almost entirely made up of ice water and a small amount of rocky rocks. Scientists believe that they began to form less than 100 million years ago when asteroids, comets and small satellites began to revolve around the planet under the influence of gravity. Subsequently, these objects met, scattered on small particles

A new study has shown that the rings of Saturn are a temporary feature of the planet and eventually disappear after 300 million years. After all, their mass is reduced to a maximum speed and the ice in their composition falls on the planet under the effect of gravity. The team of researchers at the Romanian Romanian Sapienza University, led by Lichiano Yess, used NASA data collected by the Cassini probe to estimate the gravitational field between Saturn and the rings. In fact, they drew attention to the data of the "grand finale" of the device when it passed near the ring and began to penetrate the atmosphere of the planet. , burning gradually.

"The relationship between the weight of the rings and their large enough," said an Italian scientist.

He explained that there is a flow of "polluting particles" around Saturn, which settle on the rings with a steady pace. After evaluating the mass, the scientists were able to calculate the number of particles retained and the number of years during which the rings could accumulate them. It has turned out that the main feature of Saturn is only 10 to 100 million years old.
