M42 – The Orion Nebula

The Great Orion Nebula is visible to the naked eye in the night sky as the middle "star" in Orion's sword, which are the three stars located below his belt.

M42 is a stellar nursery, where new bright blue stars are in the process of forming. It is located at a distance of approximately 1,340 light years from Earth, and is the closest region of massive star formation to us. The M42 nebula is estimated to be 24 light years across. North is toward the left.

The blue reflection nebula north of M42 is NGC1977, also called the "Running Man Nebula."
