Haze on Saturn's Moon Titan Is Similar to Earth's Pollution
On Earth, polycyclic aromatic hydrocarbons, or PAHs, are best known as carcinogens and environmental pollutants, produced as byproducts of fuel burning. It turns out these complex hydrocarbons are also contributing to the thick orange-brown smog that cloaks Saturn's largest moon, Titan, researchers say.
With a diameter of 3,200 miles (5,150 kilometers), Titan is the second-largest moon in the solar system. It's also the only one with clouds and a dense, Earth-like atmosphere and the only known place in our solar system besides Earth to have stable liquids on its surface.
Like Earth's atmosphere, Titan's atmosphere is largely composed of molecular nitrogen, but it has only small amounts of oxygen and water. Instead, the moon's clouds, lakes and rain are made up of hydrocarbons — molecules composed of hydrogen and carbon, such as methane and ethane.
The huge amount of methane makes the haze on Titan "like L.A. smog on steroids," explained Scott Edgington, Cassini deputy project scientist based at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
