NASA’s Astronomy Picture of the Day
2023 September 26 - IC 4692: The Blue Horsehead Reflection Nebula
In today's image, we see the Blue Horsehead Reflection Nebula, which is distinct from the Horsehead nebula, a dark nebula in the constellation of Orion. This is an example of a reflection nebula where the shorter wavelength blue light is scattered off of dust grains around a hot, young star which gives the nebula its distinct color.
