Unique atmospheric chemistry explains cold vortex on Saturn's moon Titan



Washington (UPI) Nov 21, 2017
New analysis suggests unique atmospheric chemistry explains why the polar vortex on Saturn's moon Titan isn't behaving as expected. Titan is Saturn's largest moon, and is the only moon in the solar system with a sizable atmosphere. Recent observations suggest that atmosphere hasn't been behaving as predicted by models. During the winter, air in the upper atmosphere tends to warm as cold air sinks, compresses and becomes heated. However, recent readings suggest the moon's polar vortex is ... read more
