                        Astronomy Picture of the Day

    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.

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