  Sub-arcsecond resolution Chandra observations of Eta Carinae reveal a 40
arcsec X 70 arcsec ring or partial shell of X-ray emission surrounding an
unresolved, bright, central source. The spectrum of the central source is
strongly absorbed and can be fit with a high-temperature thermal continuum and
emission lines. The surrounding shell is well outside the optical/IR bipolar
nebula and is coincident with the Outer Shell of Eta Carinae. The X-ray
spectrum of the Shell is much softer than that of the central source. The X-ray
Shell is irregular and only correlates well with optical features where a
bright X-ray knot coincides with a bright feature of the Outer Shell.
Implications for the binary model of the central source are discussed.
