Gigantic Storm With Huge Tail Erupts on Saturn

27 Dec

An enormous storm has erupted in Saturn’s northern hemisphere.

Amateurs first sighted the storm earlier this month, but the Cassini spacecraft moved into a good position on Dec. 24 to photograph it from about 1.1 million miles away. Earth received the raw and unprocessed shots today.

The storm has a huge central funnel and a long tail that sweeps around Saturn’s northern hemisphere for tens of thousands of miles. A shot in blue light (left) reveals the extent of the tail, but infrared light (right) shows detail of the storm’s amorphous core. The photos were taken exactly a month after Cassini recovered from a solar-flare-induced error that temporarily silenced the spacecraft from Nov. 2 through Nov. 24.

Saturn’s weather is complex like Jupiter’s, but it’s often difficult to see such storms beneath Saturn’s hazy outer atmosphere, wrote Carolyn Porco, a planetary scientist and leader of Cassini’s imaging team, on Twitter.
