New Horizons scientists made this false colour image of Pluto using a technique called principal component analysis to highlight the many subtle colour differences between Pluto’s distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC colour camera on 14 July at 11:11 UTC, from a range of 22,000 miles (35,000 kilometres). This image was presented by Will Grundy of the New Horizons’ surface composition team on 9 November at the Division for Planetary Sciences (DPS) meeting of the American Astronomical Society (AAS) in National Harbor, Maryland.
This image from NASA’s New Horizons spacecraft focuses on a section of the informally named Serenity Chasma, part of a vast equatorial belt of chasms on Pluto’s largest moon, Charon. Scientists believe that Charon’s subsurface water-ice layer may have been partially liquid in its early history, and has since refrozen, expanded and pushed the surface outward, producing the massive chasms we see today.
