RCW 84 is an emission nebula (H II region) in Centaurus
RCW 84 is an emission nebula (H II region) in the constellation Centaurus . spans 1′. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in June.
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.
