If you were to ask what is one of the most famous nebulae or images of a nebula in astronomy it’s the great Orion Nebula or M42. This gorgeous emission nebula or diffused nebula is located about 1,344 light years from Earth in the constellation Orion, south of Orion’s belt. What’s interesting about this nebula is that it’s moving away from us at 17.5 km per second! If we were going to compare the size of our Sun or mass of our Sun to M42 it would take 2,000 solar masses. The nebula has been churning and burning hydrogen and oxygen and other elements for 300,000 years in the universe. Deep within the heart of M42 is an enormous amount of energy that is causing this beautiful glow. The source is actually a young star burning bright called the Trapezium. Looking at the temperature of this nebulous cloud it actually reaches a whopping 10,000 K or about 9,726...
