1. Emission Nebula -very high in temperature, with this type of nebula another star energises the atoms. When the atoms go back to their low energy state, the nebula glows. Usually it glows red but can also glow blue and green depending on what gases the nebula is made of. 2. Reflection Nebula -a reflection nebula does not give of any radiation of it’s own. It reflect light and energy from nearby stars. They are usually blue because of their structure. 3. Dark Nebula - this type of nebula is a very thick cloud that blocks nearly all light from stars and other objects that produce light. They are usually seen close to reflection nebulae and emission nebulae. 4. PlanetaryNebula - after a red giant is old enough it sheds it’s outer layer and becomes a white dwarf. The outer layer that the red giant got rid of, becomes a planetary nebula which is usually in the shape of a hourglass and a lot of people including scientists, call them ‘butterfly wings’. 5. Supernova Remnant - when a supernova explodes and all the mass inside the star gets blown away. All the gases inside the supernova, are what creates the nebula. |
