Saturn’s moon Enceladus. Awesome.
Astrophile: Flaring Fairy Lights of Saturn’s F Ring
Object: Saturn’s F ring
Composition: Crystals of ice
Brightness: Variable; sparkly
One of Saturn’s rings is flaring and fading in a very strange fashion. When Voyager 1 visited the planet in 1980, the ring was faint, but it sparkled with bright spots. By the time the Cassini mission arrived in 2004, the spots were gone – but the ring as a whole had grown twice as bright.
