These red, orange and green clouds (false color) in Saturn’s northern hemisphere indicate the tail end of the massive 2010-2011 storm. Even after visible signs of the storm started to fade, infrared measurements continued to reveal powerful effects at work in Saturn’s stratosphere.

NASA Spacecraft Sees Huge Burp at Saturn After Large Storm
NASA’s Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet’s upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.
Data from Cassini’s composite infrared spectrometer (CIRS) instrument revealed the storm’s powerful discharge sent the temperature in Saturn’s stratosphere soaring 150 degrees Fahrenheit (83 kelvins) above normal. At the same time, researchers at NASA’s Goddard Space Flight Center in Greenbelt, Md., detected a huge increase in the amount of ethylene gas, the origin of which is a mystery. Ethylene, an odorless, colorless gas, isn’t typically observed on Saturn. On Earth, it is created by natural and man-made sources.
