Orion Nebula
The Orion nebula is one of the Messier object on his list of messier objects. The Messier number of the Orion nebula is M42. As it says in its name it is a nebula. The Orion Nebula is one of the closest stellar regions to the Earth it is been guessed that it is only 1,500 light years away. The Orion Nebula is located in the Orion constellation. The Orion Nebula is also a pretty young star cluster, with an age of less than one million years. It has even been though that some of the younger stars within the cluster are only 300,000 years old.

When all of the stars are done being born, what will remain is a clump of a few hundred to a thousand stars which are all roughly the same age. These stellar siblings are dominated by a few very massive, very bright stars called the Trapezium. The Trapezium is made up of just a few stars, but it outshines all the rest of them combined. Orion is mostly hydrogen, in both neutral and ionized states, with a fair quantity of dust. It does contain significant amounts of other elements; one of these other elements is oxygen. (Dolan) Orion is due south and highest in the sky around midnight in middle December. The stars return to the same place in the sky some 4 minutes earlier each night, or 2 hours earlier each month. So look for Orion to be highest up around 10 p.m. in mid-January and 8 p.m. in mid-February. Another time people notice Orion is around the months of August and September, when it appears in the east before dawn.
