Since its discovery in 1930, Pluto has been a speck of light in
the largest ground-based telescopes. But NASA's Hubble
Space Telescope has now mapped the dwarf planet in
never-before-seen detail. The new map is so good, astronomers
have even been able to detect changes on the dwarf planet's
surface by comparing Hubble images taken in 1994 with the newer
images taken in 2002-2003. The task is as challenging as
trying to see the markings on a soccer ball 40 miles away.
