Term Definition
Becklin-Neugebauer Object
One of the brightest of all astronomical sources of infrared radiation. It was discovered by Eric Becklin and Gerry Neugebauer in 1967 and is located in the Kleinmann-Low Nebula, within the Orion Nebula. It is thought to be a very young, massive star of spectral type B, hidden behind so much dust that it appears very feeble in visible light. There are other infrared sources near by in what is believed to be a region of very active star formation.
