Dust Devils in Space

NASA recently photographed a dust devil on Mars.  The alien twister is about 100 feet wide and a half a mile long.  With one of the largest tornado's record on Earth estimated to be over a mile wide, it makes this Martian twister look rather small in comparison, although dust devils are different then tornadoes.  Dust devils are powered by solar heating when the ground this creates upward movement creating a dust devil.  They tend to happen in the desert, and lack the same destructive power as a tornado.
