Nebulae

Nebulae

If you are here on this page then you are going to learn a little thing about my Earth and Space science project for this quarter. So what in the world is a Nebula? The word itself comes from the Latin language meaning "cloud".  Well Nebulae are these beautiful gigantic clouds that float around our universe like gigantic cluster of fog. The way that Nebulae are formed is when the various matter and particles that exist within the universe, also known as interstellar medium, their equilibrium breaks.This is due to a gravitational collapse which in turn causes the matter to slowly attract towards each other and clump up into what later becomes a Nebula. When this material collapses under its own weight many things form out of its own weight it can even form stars within the center. One of the reasons why we can see these beautiful clouds of dust is because of the ultraviolet radiation they emit when they concentrate on one spot. As these wavelengths hit earth they allow us to detect the Nebula that emits it from the dark and distant space. A Nebula is primarily made out of dust, hydrogen, helium and other different ionized gases.
