See: https://en.wikipedia.org/wiki/IGR_J11014-6103#/media/File:Lighthouse_nebula.jpg IGR J11014-6103 has the largest observed jet in the Milky Way. What are the basic mechanics IGR J11014-6103?: How fast is this neutron star pulsar moving with respect to the center of the cloud (1000 km/s?) and how far is the neutron star from the cloud center (60 ly?) Age of the explosion (15,000 years ago?) Length of jet (big part - 37 ly?) ? Speed of the jet (0.8c)? Are these 5 numbers consistent? Is there a technique to measure its mass?
