Rapid outflows, launched in antiparallel directions, roughly perpendicular to an accretionary disk found circulating around a central gravitating mass. The nature of the mechanism for the formation and collimation of jets is still a matter of controversy. Many believe that strong magnetic fields generated in the accretion diskDisk-shaped cloud of gas and solids in orbital motion around a central protostar or some other massive central body.
