Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

    [2]The picture shows Pluto in enhanced colors and high resolution and
     seen by the passing New Horizons spacecraft in 2015. Please see the
                 explanation for more detailed information.

   Explanation: [6]Pluto is more colorful than we can see. Color data and
   high-resolution images of our Solar System's most famous [7]dwarf
   planet, taken by the robotic [8]New Horizons spacecraft during its
   [9]flyby in 2015 July, have been digitally combined to give an
   [10]enhanced-color view of this ancient world sporting an unexpectedly
   young surface. The [11]featured enhanced color image is not only
   [12]esthetically pretty but [13]scientifically useful, making surface
   regions of differing chemical composition visually distinct. For
   example, the light-colored heart-shaped [14]Tombaugh Regio on the lower
   right is clearly shown here to be divisible into two regions that are
   [15]geologically different, with the leftmost lobe [16]Sputnik Planitia
   also appearing unusually smooth. After Pluto, New Horizons continued
   on, shooting [17]past asteroid Arrokoth in 2019 and has [18]enough
   speed to escape our [19]Solar [20]System completely.
