Description
Seagull nebula IC 2177. This optical image shows the seagull's head (round, centre) and shoulders (lower left). IC 2177 is a diffuse emission nebula on the boundary of the Canis Major and Monoceros constellations. Emission nebulae are clouds of gas that emit light when ionised by the radiation of hot young stars embedded within them. The composition of the gas cloud can be deduced by the colour of the light emitted; the Seagull nebula emits predominantly red light because of high proportions of hydrogen.
