Titan's Haze Acts as Ozone Layer

Titan appears to be more like Earth all the time, and a new understanding of Titan's hazy atmosphere could provide clues to the evolution of Earth's early atmospheric environment and the development of life on our home planet. Researchers have discovered a series of chemical reactions on Saturn’s largest moon that may shield the moon’s surface from ultraviolet radiation, similar to how Earth’s ozone layer works. The reactions may also be responsible for forming the large organic molecules that compose the moon’s thick and hazy orange atmosphere.
