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.
Pluto’s day is 6.4 Earth days long. The dwarf planet’s largest moon, Charon, also rotates once every 6.4 days as the two worlds are tidally locked to each another. This sequence of images from the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera on NASA’s New Horizons spacecraft shows us full rotations of the two bodies.
Earlier this year scientists presented evidence for Planet Nine, a Neptune-mass planet in an elliptical orbit 10 times farther from our Sun than Pluto. New research examining theories how this planet could end up in such a distant orbit finds that most scenarios have low probabilities. Therefore, the presence of Planet Nine remains a bit of a mystery.
Many of you may have tracked down an asteroid with binoculars or a telescope, but have you ever seen one with the naked eye? If not, then June presents you with an opportunity to see the brightest, 4 Vesta, at a close opposition. What’s more, ringed planet Saturn lies close by to act as a convenient guide.
