A counter-jet in the radio galaxy Cygnus A is discovered. This follows the earlier achievement of the discovery of the relativistic jet that emanates from the active galactic nucleus (a discovery that was made through their new methods of image processing at the Very Large Array (VLA) at NRAO). A related project, a detailed polarization map of the radio galaxy, has also been completed. A new observing project, one of the largest programs ever undertaken at the VLA, has been begun to extend these methods to a larger selection of radio galaxies. Searching for new gravitationally-lensed quasars, one prime example, Q0023+171, has been discovered and six promising new candidate objects are being studied in greater detail. About 4000 radio maps, taken with the VLA, are being processed as part of their program. A successful series of VLBI experiments has been conducted a 7 mm wavelength, with the intention of establishing that band for standard VLBI operations. A synthesized map at 7 mm of the active galaxy 3C84 (Perseus A) has been prepared and represents the most highly detailed map ever made of that unusual object, with a resolution of 140 micr-arc-seconds.
