The Kleinmann–Low Nebula (also known as the Orion KL Nebula) is an active star forming region. It is a cluster of stars within a molecular cloud.[3][4]

The Kleinmann–Low Nebula is the at the heart of the Orion Nebula, and is the most active star-forming region in it. Because of the thick dust surrounding it, it is observed primarily with infrared light, since visible light cannot pass through it.[3] It is named after Douglas Kleinmann and Frank J. Low, who discovered the nebula in 1967.[5]
