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

As the name  implies, this reflection of the nebula is linked to the star Rigel (the  seventh brightest star in the sky and the brightest in the constellation  of Gemini). This nebula is a very large, irregular cloud of dust and  gas that appears suspiciously like a chimera in a fictional story.

Officially known as IC 2118 in Constellation (Tower) Gemini.

The charming head nebula originally shines from reflected light from the star.

The  color of this mist is very blue not only because of the blue color of  its star, but also because the dust grains reflect the blue light more  efficiently than the red.

The same physical process that makes the sky color of the earth blue
