Rotating Titan in Infrared Light
Titan is one of the strangest places in
our Solar System.
The only moon known with
thick clouds, this unusual satellite of
Saturn
shows evidence of evaporating lakes created by methane rain.
The clouds that make
Titan featureless in
visible light
have now been pierced several times in
infrared light by the
robot Cassini spacecraft
currently orbiting Saturn.
These images have been compiled into the
above time-lapse movie.
Like Earth's Moon,
Titan always shows the
same face toward its central planet.
It therefore takes Titan about 16 days to complete one rotation.
Titan has numerous areas of
light terrain with some large areas of
dark terrain
visible near the equator.
Small areas of brightest terrain might arise from
ice-volcanoes
and have a high amount of reflective frozen
water-ice.
Titan's surface was imaged for the first time early last year by the
Huygens probe, which survived for three hours on a
cold and sandy dark region.
