The Antares and Rho Ophiuchi cloud complex

March 26, 2016

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 Ophiuchus. At an estimated distance of 131 ± 3 parsecs,this cloud is one of the closest star-forming regions to the Solar System.Some of the structures within the complex appear to be the result of a shock front passing through the clouds from the direction of the neighboring Sco OB2 association.Temperatures of the clouds range from 13–22 K, and there is a total of about 3,000 times the mass of the Sun in material.
