From recent high angular resolution (≃ 0.1 arcsec) observations of some extragalactic jets (in particular we refer to the radio, optical, and ultraviolet images of the M 87 jet, of 3C 66B, and 3C 264) it can be inferred that the synchrotron emission from the jet comes mainly from an external, quasi-cylindrical surface on which bright helical filamentary structures can be clearly recognized.
