Nebulae :: IC4603-4



Resolutions Available: 600x800 : 1200x1600 : 1800x2400
         Object IC4063-4
         Comment The Rho Ophiuchi Nebulae Complex is a giant molecular cloud of ionized hydrogen which is mostly obscured by dust. It owes its name to the triple star system that dominates this image, Rho Ophiuchi. Rho Ophiuchi is surrounded by the blue reflection nebulosity (IC4604) as the star light reflects off interstellar dust. Towards the bottom of the image, another reflection nebula has formed (IC4603), produced by the bright star SAO184376. The entire area is also littered with hundreds of dim reddish stars, which are typically very young T Tauri stars. The nebulae complex has an average distance of only 420 light years, making it one of the closest star forming regions.
