Orion Nebula

M42, often referred to as the Orion Nebula, goes by many names. In some older texts, it is called the Great Nebula, because it can be viewed with the naked eye. In even older texts, it is called Ensis which is Latin for sword. The Orion Nebula is one of the most photographed and studied objects in the sky and has provided scientists with much insight about the creation of the universe.
