It's more than just a weird shadow this time, planetary geologist Steven Ruff and geobiologist Jack Farmer have seen something on Mars that could indicate life was there.  NASA's Spirit Rover took the above image in 2008. They say that the 'cauliflower-like' deposits of minerals seen in this picture could have been formed by microbes. 

The area this photo was taken on Mars is thought to have been a center for hot springs and geyser activity.  The same kind of mineral shapes have been found in Atacama desert in Chile.  



The Atacama desert is often compared to the conditions on Mars and even used as a practice area by NASA for the real thing.
