IC 4603 V4

Description

This is the central part of the nebula IC 4603 surrounding the bright star SAO 184376 which illuminates the blue reflection nebula. IC 4603 can be seen near the very bright star Antares toward the constellation of Ophiuchus. IC4603 is one small part of the Ophiuchus cloud complex. The impressionistic effect is created by large amounts of interstellar dust, minute globs of carbon similar in size to cigarette smoke. This dust frequently occurs in the outer atmospheres of large, cool, evolved stars. Dense dust clouds are opaque to visible light and can completely hide background stars. For less dense clouds, it preferentially reflects blue starlight, effectively marking the surrounding dust boundary. Text borrowed from APOD
