   Explanation: Beautiful island universe Messier 94 lies a mere 15
   million light-years distant in the northern constellation of the
   hunting dogs, Canes Venatici. A popular target for earth-based
   astronomers, the face-on spiral galaxy is about 30,000 light-years
   across, with spiral arms sweeping through the outskirts of its broad
   disk. But this Hubble Space Telescope field of view spans about 7,000
   light-years or so across M94's central region. The sharp close-up
   examines the galaxy's compact, bright nucleus and prominent inner dust
   lanes, surrounded by a remarkable bluish ring of young, massive stars.
   The massive stars in the ring appear to be less than about 10 million
   years old, indicating the galaxy experienced a corresponding
   well-defined era of rapid star formation. As a result, while the small,
   bright nucleus is typical of the Seyfert class of active galaxies, M94
   is also known as a starburst galaxy. Because M94 is relatively nearby,
   astronomers can explore in detail reasons for the galaxy's burst of
   star formation.
