Pluto-philes (and astronomers, too) have always bemoaned the fact that the best images of the principal dwarf planet were just a fuzzy, pixelized haze. Bemoan no more. The most detailed look to date of the entire surface of Pluto has been constructed from hundreds of images taken by the Hubble Space Telescope. The images [...]

the two pictures there (top from 1994, bottom from 2002-2003) show differences which could easily result from different angles of illumination. Unless they have better arguments ...

Yep, those images sure come close to
suggesting an asymetrical body forming
into a sphere. But we must not take any
thunder away from New Horizons.

Is it nearly there:)
