Wright Mons in colour. This composite image of a possible ice volcano on Pluto includes pictures taken by the New Horizons spacecraft’s Long Range Reconnaissance Imager (LORRI) on 14 July 2015, from a range of about 30,000 miles (48,000 kilometres), showing features as small as 1,500 feet (450 metres) across. Sprinkled across the LORRI mosaic is enhanced colour data from the Ralph/Multispectral Visible Imaging Camera (MVIC), from a range of 21,000 miles (34,000 kilometres) and at a resolution of about 2,100 feet (650 metres) per pixel. The entire scene is 140 miles (230 kilometres) across.

This feature, known as Wright Mons, was informally named by the New Horizons team in honour of the Wright brothers. At about 90 miles (150 kilometres) across and 2.5 miles (4 kilometres) high, this feature is enormous. If it is in fact a volcano, as suspected, it would be the largest such feature discovered in the outer solar system.
Mission scientists are intrigued by the sparse distribution of red material in the image and wonder why it is not more widespread. Also perplexing is that there is only one identified impact crater on Wright Mons itself, telling scientists that the surface (as well as some of the crust underneath) was created relatively recently. This is turn may indicate that Wright Mons was volcanically active late in Pluto’s history.Image credits: NASA/JHUAPL/SwRI.
This processed image is the highest-resolution colour look yet at the haze layers in Pluto’s atmosphere. Shown in approximate true colour, the picture was constructed from a mosaic of four panchromatic images from the Long Range Reconnaissance Imager (LORRI) splashed with Ralph/Multispectral Visible Imaging Camera (MVIC) four-colour filter data, all acquired by NASA’s New Horizons spacecraft on 14 July 2015.
Pluto’s “icy heart” is a bright, two-lobed feature on its surface that was discovered by NASA’s New Horizons team in 2015. The heart’s western lobe, informally named Sputnik Planitia, is a deep basin generally thought to have been created by a smaller body striking Pluto at extremely high speed, but a new study suggests a different origin.
The first hints of dramatic cliffs, chasms and craters are showing up in new imagery of Pluto and its Texas-sized moon Charon as NASA’s New Horizons spacecraft prepares to bolt by the icy worlds Tuesday.
