Quick Answer
The first radio galaxy, Cygnus A, was identified in the early 1950s.
The Full Story
Cygnus A became one of the first recognized radio galaxies in the early 1950s, after radio astronomy advanced rapidly during and after World War II. It is a powerful galaxy that emits enormous amounts of radio waves from its central active nucleus and jets. The discovery showed that galaxies could be far more energetic than visible light alone suggested. Cygnus A remains one of the best-studied radio sources in the sky.
