We present the first images of Galactic O-rich supernova remnant (SNR) G292.0+1.8 from our ultra-deep 0.5 Msec Chandra observation. The deep Chandra ACIS data cover the entire SNR, revealing all the detailed substructures of the outermost boundary of the blast wave and new metal-rich ejecta features which were not detected by previous Chandra observation that had a 10 times shorter exposure and a small field of view. Our deep Chandra data also discover the spectacular structure of a torus and a jet in the central pulsar wind nebula (PWN), reminiscent of the Crab nebula. Utilizing extremely rich photon statistics, we present high-quality images of O-, Ne-, Mg-, and Si-rich ejecta, dense circumstellar medium produced by the massive progenitor's stellar winds and then shocked by the blast wave, the blast wave shock front propagating into a low-density ambient medium all around the SNR, and the fine-structure of the central PWN.
