Types Of Nebulas

Nebula is referred to as an extending astronomical object. Nebula basically means cloud in Latin and it also means a mist or a cloud of mist. A nebula is formed when basically a giant star supernova’s itself on a dwarf star. Nebula is nothing but a formation of plasmid matter, cloud of dust, particles and various gases.

There are many kinds of nebulae that are formed in our galaxy and various other galaxies. So these gaseous forms come in all shapes and sizes like we have the horse shaped nebula, a crab shaped nebula and various others. One of the types of nebulas is the globular clusters which contain very old stars. These stars are distributed through the halo of the nebula.

Emission nebulae are the kind of nebulae that have high temperature gases. The atoms observed in the cloud are ultraviolet and also emit the UV rays. Overall the nebulae look red in color because of the excessive content of hydrogen.

Reflection nebulae are clouds of dust that basically reflect the light from the nearby stars. Most of them are usually blue in color because they absorb the nearby scattered light.
Dark nebulae are also clouds of dust but they block the light and whatever is behind it cannot be seen. The horse head nebula is one of the dark nebulas that we can see.
Planetary nebulae are made of various gases and these gases are absorbed by the nebula from the nearby stars. These nebulas look like planets.

Supernova remnants are also nebulas created by the supernova explosion. The crab nebula is one of them.

What Is A Planetary Nebula ?

What-Is-A-Planetary-Nebula      A planetary nebula is formed when a star is unable to support its size and forma and starts creating fusion at its center. The gravity that is extended on the star starts affecting it and starts heating up the inner parts of it. The severe condensation and over heating will split the star and drive half of it away into the stellar wind. This kind of process can take place over a thousand years. When the whole process is complete, the remnants glow because of the heat and the distant gases. Such a nebula is called a planetary nebula. More..
