3C 405 is a powerful radio galaxy located in the constellation Cassiopeia. It is also known as Cygnus A and is one of the strongest radio sources in the sky. The galaxy is approximately 730 million light-years away from Earth and is notable for its large jets of particles that extend far beyond its host galaxy. The central engine of 3C 405 is a supermassive black hole, which is actively consuming material and producing immense energy. This energy is emitted in the form of radio waves, making it a key object of study in astrophysics. The galaxy's unique features provide insights into the behavior of galaxies and the evolution of the universe.
