| Comment |
Located in the southern constellation of Pavo is the grand spiral galaxy NGC6744. The galaxy is close to 175,000 light years across making it approximately 75% larger than our own Milky Way. From earth, the galaxy's size is the equivalent to a full moon however being so faint, it is not visible to the unaided eye. The galaxy's yellowish core is dominated by the light from old, cool stars. Beyond the core, spiral arms filled with young blue star clusters and pinkish hydrogen emission star forming regions sweep past a smaller satellite galaxy at the top left known as NGC6744A. NGC6744 is approximately 30 million light years away. Image is a L[HA+R]GB composite |
