In the ‘heart’ of Pluto is a second mountain range slightly lower compared to the previous year: its icy peaks ranging up to 1,000-1,500 meters high, are located between the plain Sputnik and a region more highly cratered dark. This is revealed by close-up images taken by NASA’s New Horizons spacecraft on 14 in July from a distance of 77 thousand kilometers.
The mountains just discovered are located near the southwestern edge of the region at heart nicknamed Tombaugh: are further west than the plain ice Sputnik, and 110 kilometers north-west first mountain range discovery of Pluto, the mountains Norgay.
With the detail of the images it is possible to reconstruct the entire topography of the surrounding area along the western margin of the region Tombaugh. “There is a significant difference between the appearance young icy plains to the east and the rich dark soil and craters which lies further west, “says Jeff Moore, head of the team of geologists of the New Horizons mission at NASA’s Ames Research Center in Moffett Field, California. “He ‘in place a complex interaction between the materials lighter and darker ones that are still trying to understand,” adds the expert. While the plain ice Sputnik seems to be relatively young (according to initial estimates may have formed less than 100 million years ago), the darker region could instead go back to billions of years ago
