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.

   Explanation: [8]Mimas, small 400 kilometer-diameter moon of Saturn, is
   host to 130 kilometer-diameter [9]Herschel crater, one of the larger
   impact craters in the entire Solar System. The robotic [10]Cassini
   spacecraft orbiting Saturn in 2010 recorded [11]this startling view of
   small moon and big crater while making a 10,000-kilometer record close
   pass by the diminutive [12]icy world. Shown in contrast-enhanced false
   color, the image data reveal more clearly that Herschel's landscape is
   colored slightly differently from heavily cratered terrain nearby. The
   color difference could yield surface composition clues to the violent
   [13]history of Mimas. Of course, [14]an impact on Mimas any larger than
   the one that created the 130-kilometer Herschel might [15]have
   destroyed the small [16]moon of Saturn.
