We present a dramatic, close-up view of the stripping and potential destruction of the cool-core of the Ophiuchus Cluster, the second brightest galaxy cluster in the sky in hard X-rays. The X-ray emission from the cluster exhibits a comet-like morphology extending to the north, indicative of ram-pressure stripping caused by the rapid motion of the core through the ambient cluster gas. The cluster exhibits the strongest central temperature gradient of any massive cluster observed to date: the temperature rises from 0.7 keV within 1 kpc of the brightness peak, to 10 keV by 30 kpc. A strong metallicity gradient is also observed within the same region, as well as a coherent ridge of enhanced metallicity trailing the cool-core. This supports a picture in which the outer parts of the cool-core have been stripped by ram-pressure due to its rapid motion. Within the central 10 kpc radius, multiple small-scale fronts and a complex thermodynamic structure are observed, indicating significant motions. These were probably excited by the separation of the X-ray peak from the cD galaxy and its associated dark matter potential.
