Abstract: We report on Chandra X-ray observations of the eclipsing binary millisecond pulsar B1957+20 in which we detected a narrow X-ray trail. The X-ray nebula lies interior to the known Hα bow-shock nebula and its existence proves the long held assumption that millisecond pulsars have relativistic winds. Unresolved X-ray emission at the location of the pulsar is also detected which we use to show that millisecond pulsar winds are not very dissimilar to those of the normal, higher magnetic field strength, pulsars.
