Image credit: NASA/JHUAPL/SwRI.New Horizons scientists made this false colour image of Pluto using a technique called principal component analysis to highlight the many subtle colour differences between Pluto’s distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC colour camera on 14 July at 11:11 UTC, from a range of 22,000 miles (35,000 kilometres). This image was presented by Will Grundy of the New Horizons’ surface composition team on 9 November at the Division for Planetary Sciences (DPS) meeting of the American Astronomical Society (AAS) in National Harbor, Maryland.
The true size of Pluto has been debated since its discovery over 85 years ago. New Horizons’ mission scientists can now answer that question with certainty, confirming that Pluto is larger than all other known Solar System objects beyond the orbit of Neptune.
Opening a new era, NASA’s $1.5 billion Parker Solar Probe is on its way to a close encounter with the sun, repeatedly flying through the star’s outer atmosphere to find out what heats up the corona and accelerates the solar wind
Two of Pluto’s mini-moons, the mysterious Nix and Hydra, have transitioned from featureless points of light into their own worlds with new imagery from NASA’s New Horizons spacecraft.
