A nebula is an interstellar cloud of dust, hydrogen gas and plasma. Originally nebula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy was referred to as the Andromeda Nebula before galaxies were discovered by Edwin Hubble). Nebulae often form star-forming regions, such as in the Eagle Nebula. This nebula is depicted in one of NASA's most famous images, the "Pillars of Creation". In these regions the formations of gas, dust and other materials 'clump' together to form larger masses, which attract further matter, and eventually will become big enough to form stars. The remaining materials are then believed to form planets, and other planetary system objects.

Pillars of Creation... Where stars are born. :) This video is amazing. Incredible images and a nice song to go with it. It's just amazing what is out there. Tell me...I heard once that the colors are enhanced later. I heard that some things we see don't even have color but we add later? Is this true? One day I'll have to look that up. Not now....I'd rather just enjoy.
