Most galaxies are clumped together in groups or clusters, but NGC 6503 is in a lonely position at the edge of a strangely empty patch of space called the Local Void. The Local Void is a region of space over 150 million light-years across that is essentially empty of stars or galaxies. NGC 6503 is 18 million light-years away from us in the constellation Draco. It’s about 30,000 light-years across or a third of the size of the Milky Way.
