Looking at the nebula is really amazing and very enjoyable, and we can only be dazzled and admired.
The origin of the word nebula is the Latin word for cloud. The nebula is not just a huge cloud of dust, hydrogen gaseous, helium and plasma. It is also often considered an incubator of stars, the place where the stars were born. Between distant galaxies and these massive clouds
For a time scientists and astronomers were aware that outer space was not entirely empty
In fact, it is composed of gas and dust particles known as the Interstellar Medium (ISM), roughly 99 percent of the components of this medium are gas, 75 percent of its mass is hydrogen and the other 25 are helium
Origination
The nebula is formed when parts of the astral medium undergo a gravitational collapse, where mutual attractions cause matter to be grouped together into denser regions
From here, stars can consist of the center of the material's collapse, where its UV radiation causes the surrounding gases to be visible at optical wavelengths
Most of the nebulae are very large, measuring up to hundreds of light years in the diameter, a unit of longitudinal measurement of superpowers
Crab Nebula

Crab Nebula (NGC 1952) in Taurus is probably the most supernova supernova remnant of fame in the sky. What we see now is the remains of the wreckage of this huge explosion.
The crab nebula as it appears is more like a complex network of glowing filaments of ionized hydrogen gas woven amid a bluish glow from the debris of dust and gases.
It is estimated that the nebula from the Earth is approximately 6,500 light-years away
