New views of Pluto
dwarf planets beyond Neptune,
Hubble Space Telescope
Maps of Pluto generated from Hubble ACS images gathered over 2002 and 2003 show a curious pattern of bright and dark spots across its surface, superimposed on a more neutral and bright color covering the northern hemisphere (where it was currently spring) and darker and more variegated color near the equator.
