   Explanation: [9]Image data from the Hubble Space Telescope, the
   European Southern Observatory, and small telescopes on planet Earth are
   combined in this magnificent portrait of face-on spiral galaxy Messier
   61 (M61). A mere 55 million light-years away in the Virgo Cluster of
   Galaxies, [10]M61 is also known as NGC 4303. It's considered to be an
   example of a barred spiral galaxy similar to [11]our own Milky Way.
   Like other spiral galaxies, M61 also features sweeping spiral arms,
   cosmic dust lanes, pinkish star forming regions, and young blue star
   clusters. The bright galactic core is offset to the left in this [12]50
   thousand light-year wide close-up.
