Hubble imaged nearly the entire surface of Pluto, as it rotated through its 6.4-day period, in late June and early July 1994. The two smaller inset pictures at the top are actual images from Hubble. North is up.
The larger images (bottom) are from a global map constructed through computer image processing performed on the Hubble data.
The map, which covers 85% of the planet's surface, confirms that Pluto has a dark equatorial belt and bright polar caps.
