Abstract: We report the discovery of a luminous, mini radio halo of ~240 kpc dimensionat the center of a distant cluster of galaxies at redshift z = 0.131. Ouroptical and multi-wavelength GMRT and VLA observations reveal a highly unusualstructure showing a twin bubble-like diffuse radio halo surrounding a clusterof bright elliptical galaxies; very similar to the large-scale radio structureof M87, the dominant galaxy in Virgo cluster. It presents an excellentopportunity to understand the energetics and the dynamical evolution of suchradio jet inflated plasma bubbles in the hot cluster atmosphere.
