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.

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.
Pluto is thought to possess a subsurface ocean, which is not so much a sign of water as it is a tremendous clue that other dwarf planets in deep space also may contain similarly exotic oceans, naturally leading to the question of life, said one co-investigator with NASA’s New Horizon.
Three years outbound from Pluto, NASA’s New Horizons spacecraft is homing in on a Kuiper Belt object dubbed Ultima Thule for a dramatic New Year’s Day flyby, the first by any space probe in the extreme outer solar system.
