[2] Hot stellar winds circulate off large, young, stars in Orion's nebula and heat the surrounding gas.

[4] Between 1972 and 1973 a large amount of maps were secured with the Steward and Catalina Observatories telescopes.

The temperature of the dust surrounding the Kleinmann–Low Nebula calculated to be approximately 70 Kelvin.

The nebula is estimated to be rather cool at less than 600 Kelvin, yet extremely active when viewed in the far infrared range.

[4] The Kleinmann-Low nebula is rich in the molecules HCOOCH3, CH3OCH3 and deuterated methanol, and abundant with nascent stars and planetary systems.
