Becklin-Neugebauer object
The first star to be discovered using infrared detection methods. This star is deeply embedded within the Orion star forming nebula. It is invisible at optical wavelengths because the light is completely scattered or absorbed due to the high density of dusty material in the Orion nebula. Investigation has shown that the Beckin-Neugebauer object has a spectral classification of type B and is currently on the main sequence of stellar evolution.
