Burnham's Nebula

Burnham's Nebula is the popular name for the small nebula that surrounds the star T Tauri. It was first reported by Shelburne Burnham in 1890, nearly 40 years after the discovery of T Tauri itself. T Tauri was then shining feebly at 14th magnitude – at the limit of most telescopes of the time. The condensed nebula appeared to be about 4" in size in its longest dimension. T Tauri has been brighter than 10th magnitude since the early 20th century making this feature very hard to detect. Burnham's Nebula can be discerned in an overexposed image of the star as a bulge extending about 10" from the variable. Unlike Hind's Variable Nebula, it is not believed to be a reflection nebula.
