The Chandra X-ray Observatory has provided a wealth of new observations of galactic and extragalactic supernova remnants with unprecidented angular resolution. Highlights of observations of the remnants RCW103, G292+1.8, SN1987A, Vela, SgrA East and N103B will be presented. The central object, usually thought to be a pulsar, has been studied in several of these remnants, in particular the Central Object in RCW103 has shown a remarkable degree of intensity variability for a typical neutron star. The expansion and rapid intensity increase in SN1987A has been measured, but with no evidence thus far of a central neutron star. The remnant detected at the position of the radio remnant SgrA East, exhibits unusual properties, perhaps because the supernova occurred in a dense environment. The remnant may be responsible for the very low X-ray emission from the 2 million solar mass black hole forming SgrA*. This work is supported in part by NASA contract NAS8-38252.
