The colorful region around Rho Ophiuchi (above right of center, embedded in blue nebulosity). Blue areas are dust lit up by hot blue stars (reflection nebulae), red areas are glowing hydrogen clouds (emission nebulae), and dark areas are dust clouds. The brightest star is Antares (below center), and to its lower left and upper right are Tau and Sigma Scorpii, respectively. M4 is just to the right of Antares.
