Rho Ophiuchi - details in description

Rho Ophiuchi Cloud Complex

........................................................

Located at about 500 light-years from Earth, Rho Ophiuchi is undoubtedly one of the most spectacular and colorful parts of the night sky.

Emission nebulae, reflection nebulae, dark nebulae or star clusters, all can be found in this small part of the sky. There is also a star nursery, practically the closest to Earth, and not to forget Antares (in the yellow area of the attached photo), a giant star, 700 times larger than the Sun, and 10,000 times brighter.

A book could be written about this area, so I will stop here with the description. I hope I will be lucky enough to repeat the experience at the next new moon.
