Main panel: composite RGB image of WISE images and X-rays. Channel bands: blue = EPIC 0.3–8.0 keV; green = 3.4 μm; red = 22 μm. We indicated the XMM-Newton pointing and the L1688 region which has been extensively studied. ρ Ophiuchi sits at the center of a ring of warm dust that has likely been cleared by its stellar winds. Inset image: composite RGB image of EPIC MOS and PN. Channel bands: red = 0.3–1.0 keV; green = 1.0–3.0 keV; blue = 3.0–8.0 keV. Different colors of the XMM-Newton sources indicate soft (yellow) or hard (blue) X-ray spectra.
