ABSTRACT
The article reports on the antigreenhouse effect that has been discovered on Titan, Saturn's largest moon. Titan, the largest of Saturn's moons, is kept warmer than it would be otherwise by the greenhouse effect of its thick atmosphere. But it would be even warmer if it were not for an "antigreenhouse" effect, caused by a haze layer high in the Titanian stratosphere. This mimics the global cooling effect caused by dust from volcanoes on Earth, and the possible effect of nuclear winter. Planetary scientists were already intrigued by Titan's atmosphere before these new discoveries were made. It is rich in nitrogen and resembles the atmosphere of the Earth before it was modified by living organisms.
