The Seagull is near Sirius, the main star in the constellation Canis Major. The region also includes NGC 2327 – a compact, dusty emission region with an embedded massive star that forms the bird’s head and IC 2177 – forming the sweeping arc of the seagull’s wings. The image is dominated by the reddish glow of atomic hydrogen and is about 3,800 light-years away.
