  Clusters of galaxies are excellent laboratories for studying recurring
nuclear activity in galactic nuclei since their hot gaseous medium can vastly
prolong the detectability of their radio lobes via better confinement. We
report here a multi-band study of the sparsely studied galaxy cluster Abell
980, based on our analysis of {\it{Chandra}} X-ray and the GMRT (150 and 325
MHz) and EVLA (1.5 GHz) radio archival data, revealing an unusually rich
phenomenology. It is shown to be a quasi-relaxed cluster with a cool core
($T\sim4.2$ keV) surrounded by a hot and extensive intracluster medium (ICM) at
$T\sim6.8$ keV. The radio emission shows a rich diversity, having (i) two large
diffuse sources of ultra-steep spectrum (USS), extending to opposite
extremities of the ICM, each associated with an X-ray brightness discontinuity
(cold front), (ii) a bright radio-double of size $\sim55$ kpc coinciding with
the central BCG, and (iii) a diffuse radio source, likely a mini-halo of size
$\sim110$~kpc around the BCG which possesses a huge ellipsoidal stellar halo of
extent $\sim 80$~kpc. The association of cold fronts with two highly aged (~
260 Myr) USS sources in a cool-core cluster, makes it a very rare system. These
USS sources are probably radio lobes from a previous episode of jet activity in
the BCG, driven buoyantly towards the outskirts of the X-ray halo, thereby
creating the cold fronts. A deeper radio image of this cluster may provide a
rare opportunity to verify the recently proposed alternative model which
explains radio mini-haloes as the aggregate radio emission from Type I
supernovae occurring in the giant stellar halo extended across the cluster
core.
