Reflection Nebula IC426
IC 426 is a reflection nebula in the constellation of Orion. Reflection nebulae often look a ghostly bluish color because they reflect scattered light from bright stars nearby (the red light is absorbed by dust in the nebula). Mintaka, the westernmost star in the belt of Orion, is thought to be the star illuminating IC 426.
