The Orion Nebula (also known as Messier 42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of about 1,344 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

The Asterism Observing Program has been updated with new asterisms to observe. Today, 5 new asterisms were added to the list, making the total number of asterisms to choose from 114. You only need to observe 100 to get the Program's Award Certificate and Pin.
