This new image of an area on Pluto’s largest moon Charon has a captivating feature — a depression with a peak in the middle, shown here in the upper left corner of the inset. The image shows an area approximately 240 miles (390 kilometres) from top to bottom, including few visible craters. The image was taken at approximately 10:30 UTC (11:30am BST) on 14 July 2015, about 1.5 hours before closest approach to Pluto, from a range of 49,000 miles (79,000 kilometres).

This image is heavily compressed; sharper versions are anticipated when the full-fidelity data from New Horizons’ Long Range Reconnaissance Imager (LORRI) are returned to Earth.
The rectangle superimposed on the global view of Charon shows the approximate location of this close-up view.

Geologists said Thursday they are bewildered by images from NASA’s New Horizons spacecraft baring unseen landscapes on Pluto with unexpected “snakeskin” textures, colourful chasms routing through ancient landforms, and vivid new views of apparent glacial flows.
The long-awaited fly-by of Pluto by the New Horizons spacecraft, on 14 July 2015, was an event 85 years in the making, following Pluto’s discovery by Clyde Tombaugh in 1930. Since then, Pluto has gone from planet to dwarf planet, but despite protestations from the New Horizons team, its reclassification never really changed the mission or the importance of what it would find at Pluto.
Pluto’s “icy heart” is a bright, two-lobed feature on its surface that was discovered by NASA’s New Horizons team in 2015. The heart’s western lobe, informally named Sputnik Planitia, is a deep basin generally thought to have been created by a smaller body striking Pluto at extremely high speed, but a new study suggests a different origin.
