SPACE PHOTOS THIS WEEK: Blurry Volcano, Gored Ring, More

April 22, 2009--It may not seem like it, but this image of Mars's Pavonis Mons volcano is actually in sharp focus.

The blurry appearance is due to a deep coating of dust, deposited in part by giant dust storms. The winds in the thin atmosphere at Pavonis's lofty summit are generally too feeble to blow away the dust completely.
