RCW 110 is an emission nebula (H II region) in Scorpius
RCW 110 is an emission nebula (H II region) in the constellation Scorpius . spans 7′. It is a telescope object, 6 inches or larger, and it is highest in the evening sky in July.
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.
