Titan
Titan is one of the more interesting objects
to scientists in the solar system. The Cassini mission on the way
to Saturn has a probe that will descend through the clouds of Titan and
hopefully provide a wealth of data on the moon. The nearly Mars-sized satellite
has an atmosphere that is four times more dense than Earth's.
What's more, it is covered in a hydrocarbon haze, and may be representative
of what Earth was like early in it's history. This was photographed
at an infrared wavelength that the atmosphere was transparent at.
The minimum surface feature discernible is 360 miles across. The
white blob is a surface feature is approximately the size of Australia.
