The
radio image shows striking jet-like structures that flare out from the center
of the galaxy. These structures have been traced well beyond the galaxy
out to distances of 600,000 years. The total length of the radio jet shown
here is about ten arc minutes, or about 30,000 light years in length. The
radio emission is produced by the synchrotron process, in which high energy
electrons radiate as they spiral around the magnetic field of the galaxy.
Angular size of box = 12.5 arc min corresponding
to 42,000 light years |
