Nebula

Nebula Nebula is found in space which is a cloud of dust particles and gasses. Nebula is a latin word for cloud. Such galaxies called extragalactic Nebulae only for the cloud of dust and gases in the Milky Way and other galaxies. they classify into to main types, diffuse Nebulae and planetary nebulae. Both types are called gaseous nebulae.

Diffuse Nebulae Diffuse Nebula is most likely to occur when it is near extreemly hot star. The U.V light from the star raises the gas to a higher state to make atom from the nebula and enables that mass to send off or give out light. A diffuse nebula may happen near a cool star this mean that the star is to weak to give off U.V light. The dust particles on the nebula reflect starlight. If a diffuse nebula is not near any stars it dosen't give or recieve enough light to be visible. In fact, its dust particles block out the light from the stars behind them.

Planetary Nebula Planetary nebula looks like a ball of cloud made if dust and gasses thats around a star. these happened when a star starts to cerlaps and release parts of it outer gaseous. when you look through a telescope it seems like nebula is flat rounded and looks like a planet.
