In addition, they seemed to be much younger than the scientists had predicted.
It is by its rings that Saturn is one of the most recognizable planets of the solar system but scientists give disappointing predictions: they can disappear in less than 100 million years
According to NASA, it is very fast in the universe, considering the fact that the age of the gas giant is greater than 4 billion years.
The space agency estimates that the rings of Saturn are mainly made up of ice particles, whose size varies from microscopic grains to the tree I am at a distance of several meters in diameter
They are attracted by the gravity of the planet on the surface of Saturn, like the streams of "circular rain".
"According to our estimates, this" circular rain "for half an hour deduced Saturn's rings enough water on the Olympic pool," explains James O. Donoghue, one of the leading authors of the 39, NASA study.
Scholars have long been discussing the origins of the rings of Saturn. Some suggest that the rings formed about 4 billion years ago – simultaneously with the planet and another part of the solar system. Other specialists have advanced versions according to which the rings would have appeared in Saturn much later.
A new study shows that rings formed around the planet less than 100 million years ago
"We were fortunate to be here and now to see the system Saturn's circular, which seems to be in the middle of life, "said O & # 39; Donoghua, adding that his gigantic rings were perhaps previously owned by Jupiter, Uranus and Neptune. Today, they only have thin rings and barely noticeable
Recall that scientists found a mysterious star neutron "that should not exist" . It remains nearly 24 000 light-years from Earth in the constellation Cassiopeia.

The fluctuations are so small that the human ear does not hear them. NASA scientists have increased the sound by two octaves. And they advise to listen to the headphones. The inner probe landed successfully on the surface of Mars at the end of November.
