Abstract: We analyzed the zero-order image of a 50 ks Chandra gratings observation ofCircinus X-1, taken in 2005 during the source-s low-flux state. Circinus X-1 isan accreting neutron star that exhibits ultra-relativistic arcsecond-scaleradio jets and diffuse arcminute-scale radio jets and lobes. The image shows aclear excess along the general direction of the north-western counter-jet,coincident with the radio emission, suggesting that it originates either in thejet itself or in the shock the jet is driving into its environment. This makesCircinus X-1 the first neutron star for which an extended X-ray jet has beendetected. The kinetic jet power we infer is significantly larger than theminimum power required for the jet to inflate the large scale radio nebula.
