Bright Spot on Saturn Moon Titan Leaves Scientists in the Dark

International Cassini spacecraft has flown by Titan four times since
December, each time capturing images of the mysterious spot





Bright spot on Titan, seen in VIMS imageA large bright spot on Titan,
Saturn's largest moon, has scientists and astronomers perplexed.

The international Cassini spacecraft has flown by Titan four times
since December, and on each pass its imaging equipment - spectrometers
and cameras - has recorded a bright, semicircular area on the moon's
surface up to 550 kilometers wide.

The spot is the brightest area ever observed on Titan. Scientists
think it might be a "hot spot" - possibly caused by a recent asteroid
impact, or evidence that Titan has a warm interior. Others say the
spot could be a reflection from some unusual material on the moon's
surface, or a large mass of clouds.

Cassini's next pass by Titan on July 2 will be at night. Scientists
will be watching for a glow that would tell them the mysterious area
is hot.
