   Explanation: Big, [5]beautiful spiral galaxy NGC 6744 is nearly 175,000
   light-years across, larger than [6]our own Milky Way. It lies some 30
   million light-years distant in the southern constellation Pavo but
   appears as only a faint smudge in the eyepiece of a small telescope. We
   see the disk of the nearby island universe tilted towards our line of
   sight in this remarkably deep and detailed galaxy portrait, a
   telescopic image that spans an area about the angular size [7]of a full
   moon. In it, the giant galaxy's [8]elongated yellowish core is
   dominated by the light from old, cool stars. Beyond the core, grand
   spiral arms are filled with young blue star clusters and speckled with
   pinkish star forming regions. An extended arm sweeps past smaller
   satellite galaxy NGC 6744A at the upper left. NGC 6744's galactic
   companion is reminiscent of the Milky Way's satellite galaxy the
   [9]Large Magellanic Cloud.
