NGC 6503 is an active spiral galaxy with extensive star formation areas ( red in the photo ) of the Hubble type Sc in the constellation Dragon in the northern sky . It is estimated to be 10 million light-years from the Milky Way and about 37,000 light-years across .
The galaxy lies individually in the Local Void , a huge, empty region of space next to our local group .
Light blue regions contain newly emerging stars . Dark brown streaks of dust wind over the bright arms and center of the galaxy, giving it a mottled appearance.
The object was discovered on July 22, 1854 by the German astronomer Arthur Auwers .
