Nebulas

A nebula, the Latin word for cloud, is what we call a place where stars are born (literally). They are made up of many gases, including Hydrogen and Helium. The gases come together and form many burning balls of glowing gases called stars.
There are two different types of nebulas: Planetary Nebulas, which are usually made from gases given off by a dying star, or less frequently, by supernova remnants.
An example of a nebula made by supernova remnants is the Crab Nebula in the constellation Taurus. There are many other planetary universes, not just in our galaxy, but those ar impossible to find without incredibly strong ground-based telescopes, or the help of the Hubble.
Diffuse Nebulas are the other type of nebula. They are extremely large, often light-years in length. They have no definite shape, but that doesn't mean they can't be as magnificent as other nebulas. One famous Diffuse Nebula is the Orion Nebula, located in the constellation of Orion, the hunter. Some Diffuse Nebulas arer very dark, and impossible to see without the proper equipment, but even that doesn't stop them from being some of the most dazzling sights to see.
