A process on the basis of the Standard Theory is proposed for the origin of the energy resources in the halo of Cluster of galaxies that glow in EUV and soft X-ray wavelengths. The resonant collisions (called Z-bursts) of extremely high energy (EHE, E ≥ 1021 eV) cosmological neutrinos with primordial neutrinos in Cluster of galaxies keep supplying a reasonable amount of energy deposition ˜ 1041-42 erg/sec in Clusters in terms of low energy electrons. High energy cascades of electrons and photons are efficiently contained within the Cluster due to magnetic winding, Inverse Compton, and two-photon processes. The effectiveness of the halo-glow process is constrained by the flux of cosmic EHE neutrinos, the gravitational over-density of primordial relic neutrinos, and their finite mass values. It is shown that the Z-burst mechanism can explain some of the energetics, spatial extent and lifetime of the observed glow in the halo of Cluster, provided that the flux of cosmic EHE neutrinos is as high as producing observed EHE cosmic rays (E> 1020 eV) by the same mechanism.
