The puzzling appearance of an ice cloud seemingly out of thin air in the stratosphere of Titan has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds in the giant Saturnian moon’s hazy, brownish-orange atmosphere.
New research suggests that some of Saturn’s icy moons, as well as its famous rings, might be modern adornments. Their dramatic birth may have taken place a mere 100 million years ago. This would date the formation of the major moons of Saturn, with the exception of more distant Titan and Iapetus, to the relatively recent Cretaceous Period — the era of the dinosaurs.
By convention, mountains on Saturn’s largest moon, Titan, are named for mountains from Middle-earth, the fictional setting in fantasy novels by J.R.R. Tolkien. Unfortunately for “Lord of the Rings” fans, Titan’s highest peak is not Doom Mons, but a trio of ridges known as Mithrim Montes, where the tallest peak is 10,948 feet (3,337 metres) high.
