The Cygnus OB2 region, 3:5􀀀5 Myr old, contains one of the most signicant populations of massivestars of the Milky Way. Such stars substantially contribute to producing large scale soft (< 2 keV) diuse X-ray emission. We also detected hard (> 3 keV) diuse X-ray emission in the direction of the pulsar PSR J2032+4127. The torus-shaped emission spans a 3´x2´ jet-like structure. It is spatially coincident with the Fermi gamma-ray source 4FGLJ2032.3+4127. We suggest that the hard diuse X-ray emission is the pulsar wind nebula bearing the pulsar PSR J2032+4127, a consequence of a past core-collapse SN explosion in the region.
