radiogalaktyka

This is a radio galaxy, with a linear extent of 3.0 Mpc.

This means that it is also classified as a radio galaxy.

Once one such radio galaxy had been identified, others soon followed.

Some work has been done attempting to use radio galaxies as standard rulers to determine cosmological parameters.

This is the essence behind the connection between blazars and radio galaxies.

Though signals from radio galaxies have been detected before, the "space roar" sounds six times louder than predicted.

Like all radio galaxies, it contains an active galactic nucleus.

This indicates that it may have once been an active quasar or radio galaxy.

TN J0924-2201 is the most distant radio galaxy known to date.
