Global Mosaic and Topographic Maps of Pluto and Charon Released

Jul 11, 2018 by News Staff

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

Researchers Find Methane Ice Dunes on Pluto

This high-resolution image of Pluto was taken by New Horizons on July 14. Pluto’s surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode.

According to Zhang et al, Pluto’s atmosphere is unique among Solar System planetary atmospheres, as its equilibrium temperature is controlled primarily by solid-phase haze particles instead of gas molecules. This artist’s impression shows a view of the moon Charon through Pluto’s atmospheric haze layers above the mountain landscape of bedrock water ice covered partially with deposition of dark, reddish haze particles.

The first detection of Pluto in X-rays has been made using NASA’s Chandra X-ray Observatory. The main panel in this graphic is an optical image taken from New Horizons on its approach to Pluto, while the inset shows an image of Pluto in X-rays from Chandra. There is a significant difference in scale between the optical and X-ray images. New Horizons made a close flyby of Pluto but Chandra is located near the Earth, so the level of detail visible in the two images is very different. The Chandra image is 180,000 miles across at the distance of Pluto, but the planet is only 1,500 miles across. Pluto is detected in the X-ray image as a point source, showing the sharpest level of detail available for Chandra or any other X-ray observatory. This means that details over scales that are smaller than the X-ray source cannot be seen here. Image credit: X-ray – NASA / CXC / JHUAPL / R.McNutt et al; optical – NASA / JHUAPL.
