Nebula

                               Nebula

Nebula is one of the most beautiful objects that can be found in the known universe that even some can even be seen by our naked eyes and has so many uses that are out there like making of stars etc.

Nebula is very large and massive objects much larger than anything that is out there that even the smallest is .5-.6 light years apart that

and can few be even 12-13 year wide that are very massive in size and are also very light and less dense in nature and are mostly very bright in nature as these are also of two types 

Self bright Nebula :-

self bright nebula are hot gasses that are formed after the supernova or hyper nova explosion and are  very important in nature that is they have high amount of hydrogen or oxygen that when get hot they liberate light like hydrogen gives red and oxygen gives green and these are so massive in nature that they can even cover many stars that are out there .

Reflecting Nebula:-

These types of nebula are when they cover the stars they reflect the light that is there liberated by the stars and these distance and density of stars decide there nature of there color that sometimes even cover the light of stars.

Origin of Stars:-

Nebula are hot in nature so they collect them together to form stars that are out there they get collected and get denser and denser to form stars.

Orion Nebula:-

Orion nebula is one of the closest nebula that can even be seen by our own eyes and this has many stars forming that make it very popular among scientist as it can explain the making of stars  and this nebula also has many parts that are so bright that they emit infra and ultra rays spectrum that make this bigger than it can be seen .
