Orion Nebula (M42 and M43; NGC 1976 and NGC 1982)

"A bright emission nebula in the "sword" of Orion.
The luminous nebula is just part of a complex region of interstellar matter at a distance of 1,300 light years occupying much of the constellation of Orion. The Orion cloud is the largest such dark cloud known in the Galaxy. This is an important region of star formation, and the group of four young hot stars that make up the1 Orionis, also known as the Trapezium, are believed to be less than 100,000 years old. The sharper edges of the nebula are produced by remnants of dust. M43 (NGC 1982) is a northern section of the nebula separated from the larger part (M42; NGC 1976) by a lane of dust."
