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

 Horse Head Nebula

The horse's head nebula is part of the vast and intricate nebula
The dark molecular cloud is about 1,500 light years away
It is visible only because its foggy dust shines another brighter one
The part of the horse's head is actually part of a larger cloud of dust and can be seen stretching towards the bottom
