Saturn's moon, Phoebe, is not an asteroid but a 4.5-billion-year-old primordial body from the solar system's outer reaches, Cassini mission scientists say. Images snapped by NASA's Cassini ...

New images made by the Cassini spacecraft during its fleeting encounter with Saturn’s moon Phoebe show a battered, pockmarked sphere that may be composed primarily of ice-rich material overlaid ...

Phoebe: Discovered in August 1898 by American ... As such, it has been dubbed the yin and yang of the Saturn moons. Iapetus, like Rhea, is thought to be composed of ice and rock.

Saturn's moon Phoebe hosts water unlike any found in the solar system. Every element exists in different isotopic forms, each with different numbers of neutrons. When an extra neutron is added to ...

Phoebe, Saturn’s ninth moon, was discovered in 1898, and astronomers have been vainly looking for others ever since. Their long quest has finally been rewarded. French Astronomer Audouin Dollfus ...

Very far out, there is a faint ring in the orbit of Saturn's moon Phoebe. Material is always falling from the rings toward Saturn in a steady "ring rain." This means Saturn's stunning rings will ...

All of Saturn’s moons vie for our attention. But several astronomers are particularly beguiled by Phoebe, a mid-sized moon discovered in 1898 and whose eccentric, backwards orbit has long marked ...

is thought to originate from Phoebe, the largest of Saturn's irregular moons—and like its parent moon, the Phoebe ring orbits in retrograde. (For the full-size (enormous) version of this image ...

There is also a very faint ring in the orbit of Saturn's moon Phoebe. Launched in 1997, NASA's Cassini spacecraft entered Saturn's orbit seven years later and studied the planet until 2017.

It circles Saturn backward (compared to the other rings) and follows the path of the tiny moon Phoebe. The best views of the ringed planet came from the Cassini spacecraft, which orbited Saturn ...
