Description

The Orion Nebula is an active star forming region in our galaxy that lies approximately 1350 light years distant. Many of the stars below are very young (only several 100,000 years old) and were formed from the gas and dust you see surrounding them. Regions like this are also known as "stellar nurseries". The red regions are hydrogen gas (primary star formation gas) that have been ionized by energy from a very near star. This is also known as plasma and is the same thing you find in many televisions today. The blue/grey regions are primarily dust and some hydrogen (and other) gas that are not close enough to an energy source (star) to be ionized. As such they end up reflecting light in the blue spectrum.
