1. Recent Chandra observations of the Crab Nebula system show that the southern jet has evolved over time, with changes in position, width, and spectrum as a function of distance from the pulsar. 2. Chandra images reveal that the pulsar is not centered within the inner ring, suggesting that the ring may lie on the pulsar's axis of symmetry but at a latitude of about 5 degrees. 3. Phase-resolved spectroscopy of the pulsar with Chandra shows similarities in the variation of X-ray and gamma-ray spectral indices with pulse phase, posing a challenge to theoretical models. 4. Chandra observations were used to search for an X-ray signature of the site
