We present results of a re-analysis of archival EUVE data of the central region of the Virgo cluster. We employ the new analysis method developed by Bowyer, Berghöfer & Korpela (1999) and find diffuse emission reaching out to a distance of ≈ 13\arcmin. The spatial distribution of this flux is incompatible with a thermal plasma origin. We investigate whether this emission is due to inverse Compton scattering of relativistic electrons against the 3∘ K black-body background. We show that this emission cannot be produced by an extrapolation to lower energies of the observed synchrotron radio emitting electrons and an additional component of low energy relativistic electrons is required. In addition to discussing the diffuse EUV emission, we present an analysis of the EUV emission originating from the jet in M87.
