Clicking on the graphic above loads a 1:10 scale version of the full resolution Pluto map just published based on imagery acquired by NASA’s New Horizons spacecraft 7-14 July 2015. A link to the full resolution image for high-specification desktop computers with RAM to spare is included in the article below.

The map includes all resolved images of the surface acquired 7-14 July 2015, at pixel resolutions ranging from 40 kilometres (24 miles) on the Charon-facing hemisphere (left and right sides of the map) to 400 metres (1,250 feet) on the anti-Charon facing hemisphere (map center). Many additional images are expected in autumn 2015 and these will be used to complete the global map.
The New Horizons spacecraft flew past Pluto and its moons on July 14. For high-specification desktop computers with RAM to spare, a full resolution (18630 by 9315 pixel, 5.221MB) version of the above image is available by clicking here.
The enigmatic white features on the dwarf planet Ceres are better resolved in a new sequence of images taken by NASA’s Dawn spacecraft on May 3rd and 4th. In this closest-yet view, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. However, their exact nature remains unknown.
Scientists have determined that comets produce X-ray emission when particles in the solar wind strike the comet’s atmosphere. Recently, astronomers announced the results of a study using data collected with NASA’s Chandra X-ray Observatory of two comets — C/2012 S1 ISON and C/2011 S4 PanSTARRS — when both were relatively close to Earth.
One month after its capture into orbit around Ceres, NASA engineers working on the Dawn mission state that the spacecraft is performing flawlessly and about to start capturing optical navigation images on April 10th.
