A bright, classical double radio galaxy. Radio image from Clarke etal, ApJ 385, 173, 1992. Check the Web site of A.H. Bridle (NRAO) for a better rendition of the image and discussion of the source.


Magnetic field model for rotating dipolar field, offsett by 85 degrees from rotation axis. This particular orientation is thought to describe the Crab pulsar. The last open field lines are shown; these contain the radio loud plasma. Model by J.A. Eilek and P.N. Arendt (NMT).


Optical image of M51, the Whirlpool galaxy. A three-color reconstruction, from W. C. Keel (U. Alabama).


Optical image of the central regions of the Crab Nebula, showing the dynamic filament system around the Crab pulsar. Data by J. Hester & P. Scowen, from the HST public information Web site; check there for better pictures and more information.


Optical image, from HST, of the central dust disk in the center of the galaxy NGC 4261. Data by H. Ford & L. Ferrarese, from the HST public information Web site; check there for better pictures and more information.

Radio image of the tailed radio galaxy 1231+674, in the cluster Abell 1559. VLA image from F.N. Owen (NRAO) & M. J. Ledlow (NMSU); also O'Donoghue etal Ap.J. Supp. 72, 75, 1990.
