Data collected by the Voyager missions at the beginning of the 1980's, confirmed by new observations made by the probe Cassini, give the rings a "life expectancy" of 100 million years, NASA says.
Saturn's rings, which make this planet one of the most emblematic of the solar system, are disappearing at a rate that confirms "the worst case scenario" projected by the observations made by the probes Voyager 1 at the beginning of 1980 The information was shared by the North American Space Agency (NASA), according to which the rings are being attracted to the atmosphere by gravity and falling in the form of small particles of ice.
"We estimate that this 'rain of rings' is extracting enough water to fill an Olympic pool in less than half an hour," James O'Donoghue of NASA's Goddard Flight Center in Greenbelt, Maryland, said. "Given this information alone, the entire ring system may have disappeared in 300 million years, but if we add to that the material of the rings that the Cassini probe detected to fall on Saturn's equator, the rings may have less than a hundred million of years to live."
