Planck 850 μm dust map of the Scorpius–Centaurus region in Galactic coordinates. The Milky Way plane can be seen as a pink band over the entire image. Scorpius–Centaurus OB2 (green ellipses indicate the location of the three subgroups) is mainly above the plane and is essentially dust-free apart from the ρ Ophiuchus and Lupus I clouds (labelled). Coordinates are Galactic and given in degrees. The colour scale ranges from black (low), through green, pink, red, orange to yellow (high).
