Foggy Patches

The team detected the fog in data from NASA's Cassini spacecraft, which has been exploring the Saturnian system since 2004.

Brown and colleagues first looked at the data using a digital filter they developed that reveals details only on the moon's surface.

In the filtered images, the fog appears during the moon's late southern summer as bright, reddish-white patches hovering above the surfaces of lakes.

Those patches are not visible in images filtered to show only higher altitudes of the same region, ruling out the possibility that the patches might be clouds, which have been seen before on the large moon.

As the fog dissipates, Brown suspects, methane vapor rises higher in Titan's atmosphere to form the clouds, which to the naked human eye would look identical to clouds on Earth.

Previous studies have suggested that those clouds, in turn, pelt the surface with cold methane rain—maybe even enough to occasionally create new lakes on the Saturn moon.

The research was presented last week at the American Geophysical Union's 2009 Fall Meeting in San Francisco and has been submitted for publication in the Astrophysical Journal Letters. .
