Latest From Cassini...
Encircled in purple stratospheric haze, Saturn's largest moon,
Titan, appears as a softly glowing sphere in this colorized image
taken on July 3, 2004, one day after Cassini's first flyby of that
moon. Titan has a dense atmosphere composed primarily of nitrogen
with a few percent methane. The atmosphere can undergo
photochemical processes to form hazes.
