      Sunset on Pluto [Slide Show]

      The latest jaw-dropping images from NASA’s New Horizons mission to Pluto almost seem unreal, too vivid and majestic to exist anywhere outside of an artist’s imagination. Yet real they are, captured shortly after the spacecraft’s closest approach to the dwarf planet on July 14 and subsequently downlinked to Earth on September 13. Draped in shadow by the glancing light of a far-distant setting sun, a landscape of craggy ice mountains and flowing glaciers stretches to the horizon, blanketed by layers of haze and fog. As gorgeous as these new images are, the best may still be in store: Limits on data-transmission rates from the outskirts of the solar system ensure that more Plutonian pictures with higher resolution will be whispered back to Earth for many months to come

      • A WORLD OF ICE AND SHADOW  Taken 15 minutes after closest approach, from a distance of 18,000 kilometers, this backlit image of Pluto's surface spans a shadow-crossed stretch of land some 1,250 kilometers wide. The smooth, icy expanse of the informally named Sputnik Planum can be seen on the middle right, flanked on the left by 3.5-kilometer-high mountains of water ice... Credits: NASA/JHUAPL/SwRI
      • ZOOMING IN:  Sputnik Planum and the surrounding region appear in even greater detail in this magnified section from the preceding image. Credits: NASA/JHUAPL/SwRI
      • FOG BANKS ON PLUTO:  Zooming even farther in, to the right bottom corner of the previous image, the setting sun illuminates wispy tendrils of low-lying fog lacing the terrain, interspersed with long, fingerlike shadows cast by small hills and mountains... Credits: NASA/JHUAPL/SwRI
      • THE ACTIVE HEART OF PLUTO  This composite image provides an overhead perspective of Sputnik Planum, which forms the smooth left lobe of Pluto’s now-famous “heart,” a bright feature stretching some 1,600 kilometers across the surface... Credits: NASA/JHUAPL/SwRI

      • GLACIAL FLOWS  Originating from the rugged uplands, a glacier of what may be nitrogen ice flows through a valley (red arrows) to spill into Sputnik Planum (blue arrows) in this 630-kilometer-wide image... Credits: NASA/JHUAPL/SwRI
      • ANHYDROUS HYDROLOGY  The same region pictured in the preceding picture appears in new detail, thanks to a reprojection of the backlit, more oblique view from New Horizons’ latest imagery. Again, the red arrows indicate the glacial flow through a valley and the blue arrows reveal the flow front of the ice as it slowly spills into Sputnik Planum... Credits: NASA/JHUAPL/SwRI
