RCW 49 is an emission nebula (H II region) in Carina
RCW 49 (Gum 29) is an emission nebula (H II region) in the constellation Carina . spans 1.5°. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in April.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
RCW 49 is Gum 29 in Colin Gum's survey of southern H II regions
Colin Gum listed it in his survey of H II regions of the southern Milky Way (1955), the first photographic survey of the southern emission nebulae, made at Mount Stromlo Observatory.
