Reflection Nebula NGC 1999 in the Constellation Orion
About this Image
Reflection nebulae do not emit light on their own. They shine because of a light source embedded within, like a street lamp illuminates fog. The bright, young star left of center gives NGC 1999 its brightness. The gas and dust of the nebula is left over from the star's formation.
