This picture is an infrared image of the Rho Ophiuchi cloud complex in false color, captured by NASA's Wide-field Infrared Survey Explorer (WISE) mission. The emission nebula in the center glows bright white due to heating from nearby stars, while the red object in the bottom right is a reflection nebula caused by light from the star Sigma Scorpii being reflected off the surrounding dust. The bright pink objects just left of center are young stellar objects, many still enveloped in their own compact nebulae.Photograph credit: NASA / JPL-Caltech / WISE Team
