IGR J11014−6103, also called the Lighthouse Nebula, is a pulsar wind nebula trailing the neutron star which has the longest relativistic jet observed in the Milky Way galaxy.
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 neutron star is the source of a relativistic helical jet, which is observed in X-rays but has no detected radio signature.
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).
A counter-jet (not shown in the image) has been detected, but is much fainter, possibly due to relativistic beaming.
