This false-color image, derived from observations in infrared light by the LEISA instrument, shows where the spectral features of water ice are abundant on Pluto's surface based on two scans obtained by NASA's New Horizons on July 14, 2015.
This image from NASA's New Horizons spacecraft is the first look at Pluto's atmosphere in infrared wavelengths. The blue ring around Pluto is caused by sunlight scattering from haze particles common in Pluto's atmosphere.
This approximate true-color image from NASA's New Horizons shows hydrocarbons accumulating into small particles, a fraction of a micrometer in size, and scatter sunlight to make the bright blue haze seen in this image.
Scientists with NASA's New Horizons mission have assembled the highest-resolution color view of one of two potential cryovolcanoes spotted on the surface of the distant planet by the passing New Horizons spacecraft in July 2015.
Pluto nearly fills the frame in this image from NASA's New Horizons, taken on July 13, 2015. This is the last and most detailed image sent to Earth before the spacecraft's closest approach to Pluto on July 14.
This is a portion of a high-resolution swath of Pluto sweeping over the cratered plains west of NASA's New Horizons' encounter hemisphere and across numerous prominent faults, skimming the eastern margin of the dark, forbidding region of Cthulhu Regio.
This image from NASA's New Horizons forms a strip trending from the edge of 'badlands' northwest of Sputnik Planum, across the al-Idrisi mountains, onto the shoreline of Pluto's 'heart' feature, and just into its icy plains.
On July 14, 2015, the telescopic camera on NASA's New Horizons spacecraft took the highest resolution images ever obtained of the intricate pattern of 'pits' across a section of Pluto's prominent heart-shaped region, informally named Tombaugh Regio.
NASA's New Horizons scientists believe that the informally named feature Wright Mons, located south of Sputnik Planum on Pluto, and another, Piccard Mons, could have been formed by the 'cryovolcanic' eruption of ices from beneath Pluto's surface.
Locations of more than 1,000 craters mapped on Pluto by NASA's New Horizons mission indicate a wide range of surface ages, which likely means that Pluto has been geologically active throughout its history.
Most inner moons in the solar system keep one face pointed toward their central planet; this frame from an animation by NASA's New Horizons shows that certainly isn't the case with the small moons of Pluto, which behave like spinning tops.
NASA's New Horizons cameras have spied swarms of mysterious 'pits' across the informally named Sputnik Planum. Scientists believe the pits may form through a combination of sublimation and ice fracturing.
Scientists using NASA's New Horizons images of Pluto's surface to make 3-D topographic maps have discovered that two of Pluto's mountains, informally named Wright Mons and Piccard Mons, could possibly be ice volcanoes.
