The Rho Ophiuchi cloud complex is a dark nebula of gas and dust that is located 1° south of the star ρ Ophiuchi of the constellation an estimated distance of ± 3 parsecs, it is one of the closest star-forming regions to the Solar ce: ly ( pc) ly. Featuring the bright orange star Antares from Scorpius constellation, Rho Ophiuchi Cloud Complex is one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of light interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, . Arguably one of the most colorful and impressive regions in the sky, this image shows a 25 by 15 degree section of the Serpent Bearer constellation of Ophiuchus as well as Scorpius, the Scorpion. Prominent at the center of the image is the Rho Ophiuchi Cloud Complex. The cloud complex includes the bright yellow star, Antares, whose light reflects off the surrounding yellow nebula IC

  Rho Ophiuchi Dark Cloud is a dark nebula of gas and dust located some light years away in the constellation of Ophiuchus, making it one of the closest stellar nurseries to our planet. This image shows Rho Ophiuchi, a vast stellar nursery where new stars take shape from billowing clouds of gas, as viewed by ESA's Herschel Space Observatory. Located about light-years from us, in the constellation Ophiuchus, the Serpent Bearer, Rho Ophiuchi is one of the nearest star . The equilibrium process dust emission in the Rho Ophiuchi dark cloud is studied. The luminosity of the cloud is found to closely match the luminosity of the clouds's known embedded and external. Newborn stars peek out from beneath their natal blanket of dust in this dynamic image of the Rho Ophiuchi dark cloud. Called "Rho Oph" by astronomers, it's one of the closest star-forming regions.

Star formation in molecular clouds can be triggered by the dynamical action of winds from massive stars. Furthermore, X-ray and UV The complex of Rho Ophiuchi Dark Cloud is a patchy, multi-core cloud that spans a few degrees in the sky near the epony-mous system ˆOphiuchi. A range of distances to the cloud . New and sensitive millimeter-wave and near-infrared observation have been performed in the central regions of the (rho) Ophiuchi dark cloud. High spatial resolution observations of the optically thin C('18)O emission lines are shown to be free of self-absorption. They permit the first accurate determination of the distribution of molecular gas and allow us to estimate the mass and visual.

Introduction Located only ˘ pc from the Sun, the ˆOphiuchi dark cloud is one of the most conspicuous regions where low-mass star formation is taking place (e.g. Wilking for .   Related: Rho Ophiuchi: A Colorful Cosmic Cloud in Photos Visible to the left of Antares is the globular star cluster Messier 4, or M4, which lies far beyond the colorful cloud .
