What types of nebulae are there
[change | change source]There are a few types of nebulae types, a few of them are planetary nebulae which are formed when a star like our sun or slightly larger dies, a supernova remnant is the remains of a massive star dies, a emmision nebula is a nebula that consists of ionized gas that emits light of different colours, a dark nebula is a nebula that has dense clouds that block light from behind them, a reflection nebula is a nebula that is made of dust that reflects from nearby stars and a protosteller nebula is where new stars form from collapsing clouds of gas. There are also H II regions which are ionized hydrogen gas which intesne star formation is occouring and there are also wolf-rayet nebulas that contain massive stars that have strong steller winds.
