But, like everything in the Universe, they're not going to last forever - and now planetary scientists have discovered that they're disappearing at an incredibly fast rate.
Estimating that the "ring rain" drains an Olympic swimming pool of water every 30 minutes, the research team found that the ice circles are dying at the maximum rate estimated from observations made decades ago.
Why is this happening?
The rings are mostly composed of lumps of water ice that vary in size from microscopic grains to boulders of several yards across, the space agency said.
The entire ring system will be gone in 300 million years, and taking into account the materials falling into the planet equator, detected by NASA's Cassini spacecraft, the rings may have less than 100 million years to live.
That's a snap of the fingers in cosmic time, particularly considering Saturn is more than 4 billion years old.
The fate of the rings looks even grimmer considering research published earlier this year using Cassini data, which looked at a different, still-more-voluminous, type of infall from Saturn's rings that's descending into the planet.
"If rings are temporary", O'Donoghue said, "perhaps we just missed out on seeing giant ring systems of Jupiter, Uranus and Neptune". O'Donoghue continued from his above statement.
The rings of Saturn, a ring system orbiting about the Saturn, consist of countless small particles made nearly of water ice with a trace component of rocky material. It's like a "will they, won't they" relationship in a sitcom, very Sam and Diane. Tiny particles can get electrically charged by ultraviolet light from the Sun or by plasma clouds emanating from micrometeoroid bombardment of the rings.
In a new video, NASA Goddard explains that while we've always seen Saturn with its bold rings, the rings themselves are actually fairly young.
The Cassini and Voyager 1 and 2 missions made the observations of Saturn's so-called "ring-rain" phenomenon on which the estimates were based.
And that creates the rains down in Saturn, with gravity winning out against orbital velocity. That could mean the rings might disappear even sooner, in less than 100 million years, O'Donoghue said. That kind of scale is what makes space so fascinating. "That wasn't a complete surprise", said Connerney.
Saturn's moon Enceladus drifts before the rings and the tiny moon Pandora in this view that NASA's Cassini spacecraft captured on November 1, 2009. This mosaic shows everything from the expansive rings to the hexagonal jet stream at the north pole. Pandora, which is about (52 miles, 84 kilometers) wide, was on the opposite side of the rings from Cassini and Enceladus when the image was taken.
The team would like to see how the ring rain changes with the seasons on Saturn.
At any given moment, the majority of the water ice grains that form Saturn's rings maintain a stable trajectory.
