This is not the prettiest of astronomical objects, but I like it for the sheer amount of action that it implies - interstellar dust and hydrogen gas are blowing every which way, and star formation is occurring at quite a clip due to an ancient supernova having taken place nearby. IC 4603 - the central nebulosity in this image - can be found near Antares, but just inside the borders of the constellation Ophiuchus. The dust is illuminated by the light of SAO 184376, a bright (Mag. 7.6), pre-main sequence, B-type star, which gives us that distinctive blue of a reflection nebula.
