Extragalactic Radio Sources
The space beyond our galaxy contains billions ofother
galaxies and some of these are strong emitters
at radio wavelengths. Extra-galactic radio sources are
often divided into two groups: "normal" galaxies and
"radio" galaxies. The great Andromeda galaxy (M.3,I)
is an example of a normal radio galaxy as are the
Large and Small Magellanic Clouds. Our own galaxy
is also normal at radio wavelengths with an output of
less than 1022 watts.
The so-called "radio" galaxies have a power output of
a very different order. The second strongest radio
source is Cygnus A (Cas A is the first),a remote
galaxy located some 184 Mpc. in distance from our
Sun, with a radio output of some 1038 watts! In the
words of radio astronomy pioneer John D. Kraus:
"The tremendous magnitude of Cygnus A's power
may take on more significance if we note that the
radio wave energy radiated by Cygnus A in just one
millionth of one second is sufficient to supply all of the
world's electric power requirements for all purposes
(light, heat, mechanical work, etc.) at a million times
the present rate for the next 10 million years." That is
hot stuff!
Some other strong radio galaxies include Virgo A,
Perseus , Centaurus A, Fornax A and Hercules A.
Included elsewhere is a list of the stronger of the
known radio sources within and without the galaxy.
Some attempt has been made to indicate the nature
of the radiating object in the notes column. The
column marked "flux" will provide the reader with
some idea as to the relative strength of the various
radio sources. The values listed (under flux) are for
1400 Mhz, with the exception of those marked with an
asterisk which are for 178 Mhz. The reader should
