We report on our initial analysis of a deep 510 ks observation of the Galactic oxygen-rich supernova remnant (SNR) G292.0+1.8 with the Chandra X-Ray Observatory. Our new Chandra ACIS-I observation has a larger field of view and an order of magnitude deeper exposure than that of the previous Chandra observation, which allows us to cover the entire SNR and to detect new metal-rich ejecta features. We find a highly nonuniform distribution of thermodynamic conditions of the X-ray-emitting hot gas that correlates well with the optical [O iii] emission, suggesting the possibility that the originating supernova explosion of G292.0+1.8 was itself asymmetric. We also reveal spectacular substructures of a torus, a jet, and an extended central compact nebula, all associated with the embedded pulsar J1 124-5916.
