   Explanation: Large spiral galaxy NGC 4945 is seen edge-on near the
   center of this cosmic galaxy portrait. In fact, it's almost the size of
   our Milky Way Galaxy. NGC 4945's own dusty disk, young blue star
   clusters, and pink star forming regions standout in the sharp, colorful
   telescopic image. About 13 million light-years distant toward the
   expansive southern constellation Centaurus, NGC 4945 is only about six
   times farther away than Andromeda, the nearest large spiral galaxy to
   the Milky Way. Though this galaxy's central region is largely hidden
   from view for optical telescopes, X-ray and infrared observations
   indicate significant high energy emission and star formation in the
   core of NGC 4945. Its obscured but active nucleus qualifies the
   gorgeous island universe as a Seyfert galaxy and home to a central
   supermassive black hole.
