The science team of NASA’s New Horizons mission has produced this global map of Pluto’s largest moon, Charon. The map includes all available resolved images of the surface acquired between 7-14 July 2015, at pixel resolutions ranging from 40 kilometres (24 miles) on the anti-Pluto facing hemisphere (left and right sides of the map), to 400 metres (1,250 feet) per pixel on portions of the Pluto-facing hemisphere – the side facing the New Horizons spacecraft when it flew past the dwarf planet – at map centre. Many additional images now stored on the spacecraft’s digital data recorders are expected to be transmitted “home” in later this year and these will be used to complete the global map. The map is in simple cylindrical projection, with zero longitude (the Pluto-facing direction) in the centre.

SOHO sees bright sungrazer comet
ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, saw a bright comet plunge toward the Sun on 3-4 August 2016, at nearly 1.3 million miles per hour. The comet, first spotted by SOHO on 1 August, is part of the Kreutz family of comets, a group with related orbits that broke off of a huge comet several centuries ago.
Public invited to help name features on Pluto and its largest moon, Charon
On July 14th, NASA’s New Horizons spacecraft will flyby Pluto, offering the first close-up look at that small, distant world. You can help decide what names will be used on subsequent maps of the dwarf planet and its largest moon, Charon, as the SETI Institute announces the launch of its “Our Pluto” campaign.
