Amazing image shows Pluto`s frozen canyons
The New Horizons spacecraft captured the "ethereal scene" in July, NASA said. The image`s colors have been enhanced to provide a particularly enlightening look at the region`s topographical features.
An annotated version of the photos highlights particular canyons, pits and valleys.
The graphic below shows the area`s largest canyon, which is 45 miles wide, in yellow. A valley (marked in blue) runs along the length of the canyon floor. Several "subsidiary canyons" (shown in green) run roughly parallel and each measure about 6 miles wide. Another valley (in pink) can be seen further to the right.
Red markings "indicate locations where subsurface ice has melted or sublimated from below, causing the ground to collapse," according to NASA.
