We report the discovery of multi-scale X-ray jets from the accreting neutronstar X-ray binary, Circinus X-1. The bipolar outflows show wide opening anglesand are spatially coincident with the radio jets seen in new high-resolutionradio images of the region. The morphology of the emission regions suggeststhat the jets from Circinus X-1 are running into a terminal shock with theinterstellar medium, as is seen in powerful radio galaxies. This and otherobservations indicate that the jets have a wide opening angle, suggesting thatthe jets are either not very well collimated or precessing. We interpret thespectra from the shocks as cooled synchrotron emission and derive a cooling ageof approximately 1600 yr. This allows us to constrain the jet power to bebetween 3e35 erg/s and 2e37 erg/s, making this one of a few microquasars with adirect measurement of its jet power and the only known microquasar thatexhibits stationary large-scale X-ray emission.
