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.
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.
NASA’s New Horizons spacecraft took this stunning image mere minutes after closest approach on 14 July 2015. Seen here, sunlight filters through and illuminates Pluto’s complex atmospheric haze layers over portions of the nitrogen ice plains informally named Sputnik Planum, as well as mountains of the informally named Norgay Montes.
Five months after NASA’s New Horizons spacecraft flew past Pluto, knowledge about this distant system continues to unfold, yet the spacecraft is less than halfway through transmitting data about the Pluto system to Earth. New Horizons science team members presented the latest findings at the American Geophysical Union (AGU) autumn meeting in San Francisco.
