   Explanation: Beautiful spiral galaxy NGC 6744 is nearly 175,000
   light-years across. That's larger than [6]the Milky Way. It lies some
   30 million light-years distant in the southern constellation Pavo, with
   its galactic disk tilted towards our line of sight. [7]This Hubble
   close-up of the nearby island universe spans about 24,000 light-years
   or so across NGC 6744's central region. The Hubble view combines
   visible light and ultraviolet image data. [8]The giant galaxy's
   yellowish core is dominated by the visible light from old, cool stars.
   Beyond the core are star-forming regions and young star clusters
   scattered along the inner spiral arms. NGC 6744's young star clusters
   are bright at ultraviolet wavelengths, shown in blue and magenta hues.
   [9]Spiky stars scattered around the frame are foreground stars and well
   within our own Milky Way.
