These frozen peaks are estimated to be one-half mile to one mile (1-1.5 kilometers) high, about the same height as the United States’ Appalachian Mountains.
The mountains are located between a bright, icy plain believed to be less than 100 million years old and a dark, cratered area estimated to have been in existence for billions of years.
“There is a pronounced difference in texture between the younger, frozen plains to the east and the dark, heavily-cratered terrain to the west,” said Jeff Moore, leader of the New Horizons Geology, Geophysics and Imaging Team, said in a statement.
“There’s a complex interaction going on between the bright and the dark materials that we’re still trying to understand.”
New Horizons was 48,000 miles (77,000 kilometers) from the dwarf planet when the image was taken.
