We report the detection of a Ξ³-ray bubble spanning at least 100degΒ² in ultra-high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, implying the presence super PeVatron(s) accelerating protons to at least 10 PeV. A log-parabola form with the photon index Ξ(E)=(2.71Β±0.02)+(0.11Β±0.02)Γlog(10)(E/10TeV) is found fitting the gamma-ray energy spectrum of the bubble well. UHE sources, βhot spotsβ correlated with very massive molecular clouds, and a β¦
