   Explanation: Grand design [8]spiral galaxy Messier 99 looks majestic on
   a truly cosmic scale. This recently processed [9]full galaxy portrait
   stretches over 70,000 light-years across M99. The sharp view is a
   combination of ultraviolet, visible, and infrared image data from the
   Hubble Space Telescope. About 50 million light-years distant toward the
   well-groomed constellation Coma Bernices, the face-on spiral is a
   member of the nearby [10]Virgo Galaxy Cluster. Also cataloged as NGC
   4254, a [11]close encounter with another Virgo cluster member has
   likely influenced the shape of its well-defined, blue spiral arms.
