Saturn's rings formed shortly before, according to astronomical standards, ranged from 10 million to 100 million years, the researchers said in a study published in the journal Science, based on data sent by the American-European investigation «Cassini».
If this period seems very large in human standards, but it is small from the age of the universe, even from the times of the solar system, planet, and life on it. By comparison, dinosaurs became extinct 65 million years ago.
Space scientists have signs of the life of Saturn's rings formed by collisions of Saturn's moons with each other, or from spherical explosions near the planet. But age is certainly one of the biggest mysteries of the solar system. But Cassini, which was launched in 1997, has recently been able to collect data to calculate the age of episodes. When his mission approached, he approached a very short distance from the planet and its ring, before crashing into the atmosphere after the fuel ran out.
Thanks to the information he sent, scientists can measure the planet's gravitational strength on the ring and vice versa, and deduce the mass. Comparing this abstract with other data, scientists have determined age.
The US space agency «NASA» how scientists think, namely that the ring mass shows age, the older the greater the mass over time.
