A photograph of the Rho Ophiuchi cloud complex. The image is dominated by swirling nebulae in various colors — yellows, blues, and hints of red and pink. At lower left lies the star Antares, enveloped by a golden yellow cloud. In the upper right is Rho Ophiuchi, surrounded by a blue reflection nebula. The background is filled with countless stars of varying brightness. Dark dust lanes create striking contrasts throughout the image, particularly in the center. The overall effect is a rich, colorful cosmic tapestry of gas, dust, and stars.
