RHO OPHIUCHI cloud complex

RHO OPHIUCHI cloud complex

At the borders of constellations Ophiuchus and Scorpius, the Rho Ophiuchi cloud complex is one of the most colorful areas of the night sky. Huge clouds of gas and dust support this star-forming region a mere 460 light years away from Earth, making it one of the closest star-forming regions to us.

The blue regions shine primarily by reflected light from the blue supergiant stars, while the red and yellow regions shine primarily because of emission from the nebula's atomic and molecular gas. The dark brown regions are caused by dust grains which effectively block light emitted behind them.

Antares, the brightest star in Scorpius, is nearing the end of its life cycle. The star is beginning to puff off layers of gas, creating its own funeral shroud. Antares is about 700 times larger than our Sun.

The globular clusters M4, M80 and NGC 6144 in this photo are much older and much farther away from the Rho Ophiuchi formation. M4 is the closest globular cluster to our solar system, at approximately 7200 light years away. It has an estimated age of 12.2 billion years.
