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).

three-color reconstruction, from W. C. Keel

Optical image of the central regions of the Crab
Nebula, showing the dynamic filament system around the Crab pulsar.

from the double nuclei in the parent galaxy. This galaxy is the
central galaxy in the cluster Abell 400. Radio image from Owen etal,
ApJ (Letters), 294, L85, 1985.
