  We present results from \textit{Chandra} X-ray observations and 325 MHz Giant
Metrewave Radio Telescope (GMRT) observations of the massive and X-ray luminous
cluster of galaxies Abell S1063. We report the detection of large-scale \lq\lq
excess brightness\rq\rq\ in the residual \textit{Chandra} X-ray surface
brightness map, which extends at least 2.7 Mpc towards the north-east from the
center of the cluster. We also present a high fidelity X-ray flux and
temperature map using \textit{Chandra} archival data of 122 ksec, which shows
the disturbed morphology in the cluster. The residual flux map shows the first
observational confirmation of the merging axis proposed by earlier simulation
by \citet{Gomez2012AJ....144...79G}. The average temperature within $R_{500}$
is $11.7 \pm 0.56$ keV, which makes AS1063 one of the hottest clusters in the
nearby Universe. The integrated radio flux density at 325 MHz is found to be
$62.0\pm6.3$ mJy. The integrated spectrum of the radio halo follows a power-law
with a spectral index $\alpha=-1.43\pm 0.13$. The radio halo is found to be
significantly under-luminous, which favored for both the hadronic as well as
the turbulent re-acceleration mechanism for its origin.
