9 Jun 2013, 16:00 UTC Scientists working with data from NASA’s Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn’s largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze.

Major) Scientists working with data from NASA’s Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn’s largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze. The presence of these complex, ringed hydrocarbons, known as polycyclic aromatic hydrocarbons (PAHs), explains the origin of the aerosol particles found in the lowest haze layer that blankets Titan’s surface. Scientists think these PAH compounds aggregate into larger particles as they drift downward. “With the huge amount of methane in its atmosphere, Titan smog is like L.A. smog on steroids.” – Scott Edgington, Cassini deputy project scientist “With the huge amount of methane in its atmosphere, Titan smog is like L.A. smog on steroids,” said Scott Edgington, Cassini deputy project scientist based at NASA’s Jet Propulsion Laboratory, ...
