Methane clouds over northern seas could signal arrival of summer storms
Space news (the solar system: Saturn; Titan) – looking for evidence of clouds moving over surface of Saturn’s moon Titan –
Planetary space scientists have been looking for evidence of clouds moving over the northern hydrocarbon seas of Saturn’s moon Titan for awhile. Their planetary models of Titan predicted the movement of clouds over the northern seas, which should signal the arrival of summer storms. Near the end of July, they were provided with the proof they require in the form of images of methane clouds moving at 7 to 10 mph across the sky above the hydrocarbon seas of Titan’s northern sea Ligeia Mare. You can watch a movie showing the movement of clouds over the northern seas of Titan here.
“We’re eager to find out if the clouds’ appearance signals the beginning of summer weather patterns, or if it is an isolated occurrence,” said Elizabeth Turtle, a Cassini imaging team associate at the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. “Also, how are the clouds related to the seas? Did Cassini just happen to catch them over the seas, or do they form preferentially?”
Work continues for the team
Planetary scientists will continue to watch and study seasonal changes on Saturn’s moon Titan in order to learn more about the weather systems on other worlds and our own. This will be a job requiring patience, because a year on Titan is equivalent to 30 years on Earth, and each season lasts around seven years.
