We present results from the first extensive, spatially-resolved spectroscopic analysis of the ultra-deep 574 ks Chandra observation of M87, the dominant galaxy of the Virgo Cluster. The superb spatial resolution and extreme photon statistics allow the creation of high-resolution thermodynamic maps from the spectra of 16,000 independent regions, with the temperature and density in each region measured to better than 10 per cent. Our maps reveal dramatic and complex structure in the temperature, pressure, entropy, and metallicity maps. We study in unprecedented detail AGN-induced weak shocks, gas uplift, chemical enrichment, conduction, and the nature and spatial distribution of the multiphase plasma in M87. The Chandra data, together with high-resolution spectra from the XMM-Newton RGS and deep Halpha images, place strong constraints on the balance between heating and cooling in the galaxy and cluster core. Our results have profound implications for the fate of the coolest gas phases in clusters and the powering of Halpha filaments.
