The object consists of a neutron star with a radius of about 12 km, which formed about 10,000–30,000 years ago in a supernova explosion. The supernova explosion "kicked" the neutron star, which is now moving through space with a velocity of between 0.3% and 0.8% of the speed of light, faster than almost all other known runaway neutron stars. The pulsar is now about 60 light-years from the original supernova location.
The neutron star is the source of a relativistic helical jet, which is observed in X-rays but has no detected radio signature.[1] In the composite processed image (right) the neutron star pulsar is the point-like object with a pulsar wind nebula tail trailing behind it for about 3 light-years. The jet, aligned with the pulsar rotation axis, is perpendicular to the pulsar's trajectory and extends out over 37 light-years (about nine times the distance from the Sun to the nearest visible star). The estimated velocity of the jet is about 80% of the speed of light.
The star was initially presumed to be rapidly spinning but later measurements indicate that its spin rate is only 15.9 Hz.[2][3] This rather slow spin rate and the fact that there is no evidence of accretion suggests that the jet is neither rotation nor accretion powered. A counter-jet (not shown in the image) has been detected, but is much fainter, possibly due to relativistic beaming.[4][5] The origin of the glitch at about a third of the jet length is not known, but it might be due to the jet switching off and on or the jet orientation changing.
