The rings of Saturn were formed shortly before, according to astronomical standards, ranging from 10 million to 100 million years ago, researchers said in a study published in the journal Science, based on data sent by the European-American "Cassini" probe.
If this period seems huge on a human level, but it is small from the age of the universe, even from the age of the solar system, the planet and the life that reigns there. In comparison, the dinosaurs disappeared 65 million years ago.
Space scientists had signs of life from the rings of Saturn formed by the collision of Saturn's moons with each other or by the explosion of a globe near the planet. But his exact age was one of the biggest mysteries of the solar system. But Cassini, launched in 1997, has recently been able to collect data to calculate the age of the episodes. As he approached his mission, he approached very short distances from the planet and his rings, before crashing into his atmosphere after the fuel failure.
Thanks to the information he sent, scientists were able to measure the force of the planet's gravity on its rings and vice versa, and to deduce its masses. By comparing these summaries with other data, the scientists determined the age.
The US Space Agency "NASA" how scientists have thought, namely that the mass of the rings indicates age, the more the age of the mass increases with time.
