Nebulae. Optical image of stars in clouds of interstellar gas & dust (nebulae) in the constell- ations of Scorpius & Ophiuchus. At lower left is the Pipe dark nebula which is comprised of several smaller nebulae. At upper right is the Rho Ophiuchi nebula complex which is comprised of dark nebulae,reflection nebulae (blue) and emission nebulae (red). The bright,red star in this complex is Antares. Nebulae are interstellar clouds of dust and gas. Dark nebulae block the light from the stars behind them. Reflection nebulae reflect the light of nearby stars. Emission nebulae are excited into fluorescence by ultraviolet light from a nearby hot star | |
