A nebula is a beautiful structure at first sight. They really look amazing. But looks can be deceiving. What are these things really? How are they formed? What are they for? How big are they? I will answer all these things and more here today in this new article. Please drop a comment in case you liked it or not. Enjoy the article.
Nebulae (Plural form of ‘nebula’ is nebulae, not nebulas) are giant huge clouds of dust and gas. The gas is hydrogen in an ionized form like H+. A lot of these giant clouds are made from the gas and dust of a newly exploded dying star. Some are places where potential new stars could eventually be formed. Some nebulae are famous, such as the Omega Nebula and the Eagle Nebula in space.
These nebulae can be really very big, such as a couple of light years in size. Normal nebulae are around one to two light years in size. The really big ones could be 50 light years in diameter. In comparison to our solar system, which is around one and three fourth light years, which is around as much as 12 trillion miles or 1.2 x 1013 miles. So, we can say that a lot of stars have given their dust and gas to various nebulae all around the entire universe almost everywhere.
These nebulae are very helpful in assisting stars to form. Since stars are made of gas and dust, they form using a nebulae’s help. The leftover matter from the star is then used to make planets, asteroids and comets. When a solar system dies, it gives its gas and dust to a nebula. This creates a cycle of birth and death.
