CTB80: a galactic radio source with directed jets

The galactic radio source CTB80 shows several remarkable jets which can be traced outward to over 30pc from a point less than 0.1 pc within a central core. If the object is associated with a supernova of 1408 then the jets must move out at a velocity of 0.2 c but the morphology of the whole source suggests a significant proper motion of the central object which argues for an older age. In this case continuous ejection into the jets must have occurred for tens of thousands of years. A model involving a supernova explosion ejecting several massive path-cutting fragments is quantitatively explored, and found to be plausible.
