Description

The Orion Nebula (M42) and Running Man Nebula (M43). The Orion Nebula (M42) is a stellar nursery. New stars are in the process of forming in this part of the galaxy. There are two types of nebula shown here. The blue reflection nebula is present in NGC 1977, also called the "Running Man Nebula", in the left object. There is some reflection in many parts of the frame as well. The Orion Nebula has rich red areas of the hydrogen alpha emissions. This is a florescence, where radiation is causing clouds of hydrogen gas to glow.
