Rho Ophiuchi (Region Around Antares)
| Object |
Rho Ophiuchi region around Antares in Scorpius / Ophiuchus: The bright yellow star illuminating the yellowish area of gas/dust at lower center is the star Antares. Just to the right of Antares is the globular star cluster M4, with the reddish nebula SH2-9 just above it, around the whitish star Alniyat. The blue patch at upper center is the nebula IC4604, around the little group of stars called Rho Ophiuchi. The darkish streamers at left are dark nebulae Lynds 1688 and 1689 that are blocking light from the very dense starfields behind them. |
