Nebula's size ranges from millions of miles to hundreds of light-years in diameter. Here's some interesting facts you might have not known yet.
What is a Nebula?
Nebulae are majestic objects that look like colorful clouds. They are made of hydrogen, helium, interstellar ice, and other gasses. Initially, the label "nebula" was used to describe all of the diffused astronomical objects, even galaxies.
How do the Nebula form?
Nebulae are created in the interstellar medium, and they are the result of gasses breakdown. When gas, hydrogen, helium,ions,particles, and electrons particles clump together, they form a nebulae. They are very important.
Why are Nebulae important?
Nebulae are very important "clouds" in interstellar space. They can create stars,
planets, and even entire solar systems. Nebulae were a thing before the concept of galaxies. Therefore, nebulae are very important for the branch of astronomy, being a reference point for later discoveries.
- A dark nebula is very dense. It's seem to be obscured. An example of a dark nebula is the Horsehead Nebula.
- The Helix Nebula is the closest one to Earth.
- The nebulae outside the Milky Way are referred to as extra-galactic nebulae.
- Nebulae are also known as "Stellar Nurseries" , because stars are born in them.
- In about 5 billion years from now, our Sun will become a nebula.
