Saturn can lose his rings

New research from NASA shows that the rings, mainly made of water ice, are drawn from the gravity of the planet, and on Saturn’s surface that shines with “rain showers”.

“We estimate that this” rain “drains a host of water products that could fill an Olympic big swimming pool from Saturn’s rings in half an hour, said NASA’s James Donoghue, author of the study, in a statement.

“From this alone, the entire ring system will be gone for 300 million years, but add to this Cassini spacecraft the measured ring material detected falls into Saturn’s equator and the rings have less than 100 million years to live,” he added.

“But if the rings are temporary, maybe we just missed seeing giant ring systems of Jupiter, Uranus and Neptune, who only have narrow ringlets today!”

Dumping Water

This comes months after research released in October – which used data from the Cassini spacecraft registered before entering the planet’s atmosphere 2017 after 20 years of observation – found that the “ring rain” was like a ” nedspill “.

During the final dunk, Cassini’s Ion and Neutral Mass Spectrometer acted as the “nose” of spacecraft, directly sampling the atmosphere’s composition and structure.

According to the spectrometer layer Cassini’s nose hit the “jackpot” when it sniffed the unknown area between the planet and its closest rings. This is the key because Saturn’s upper atmosphere extends almost to the rings.

Researchers decided that complex organic compounds rain a chemical cocktail of dust from the nearest ring, D-ring, to the upper atmosphere. The spectrometer revealed the rings that would consist of water, methane, ammonia, carbon monoxide, molecular nitrogen and carbon dioxide.

“While [the spectrometer] was designed to investigate gases, we could measure the ring particles because they hit spacecraft at such high speeds they evaporated,” said Hunter Waite, principal researcher for the spectrometer on Cassini’s nose and author of the study published in the journal Science.

 What Cassini Found When It Was Killed In Saturn A Year ago

“Watercraft along with newly discovered organic compounds fall out of the rings faster than anything thought – as much as 10,000 kilograms of material per second, “he added.

“We know that bouncing material out of the rings is at least 10 times faster than we thought,” said Thomas Cravens, co-author of one of the October studies and a professor of physics and astronomy in Kansas. “If it is not filled up, the rings will not be left – you have a hole in your bucket. Jupiter had enough ring developed to the current pointed ring, and it may be for similar reasons. Rings do come and go. at some point they are gradually drained if they do not get any new material in any way. “

Saturn is about 900 million miles from the sun, which is almost 10 times as far as our own distance from the star. While one day on Saturn only takes about 10.7 hours, one year lasts 29 on earth. And this gas giant has a volume that is 700 times as big as our own planet.

Saturn’s current orientation is in line with the sun and earth (with the earth in the middle), giving us a great view of the planet and also some of its moons. With a telescope you can see even more moons and Saturn’s rings tilted at 26 degrees.
