Chandra has provided a new view of hot gas in clusters and early type galaxies. In clusters, cold merger remnants are detected crossing through cluster cores allowing new probes of the magnetic field. Supersonic mergers are seen with clear bow shocks and particle acceleration ahead of the shock. In early type galaxies, a variety of interactions between hot plasmas (sometimes radio emitting and sometimes radio quiet) and X-ray emitting gas is seen. Chandra images combined with radio observations show features ranging from buoyantly rising bubbles to supersonic shocks in early type galaxy atmospheres.
