Radio galaxies may be the oldest galaxy systems, providing clues to the evolution of galaxies.
The two giant radio galaxies found with the MeerKAT telescope. In the background is the sky as seen in optical light. Overlaid in red is the radio light from the enormous radio galaxies, as seen by MeerKAT.

Based on what we currently know about the density of giant radio galaxies in the sky, the probability of finding two of them in this region is extremely small.
A precursor to the Square Kilometre Array- the MeerKAT telescope - is being built right now and remarkable progress has been made in the last 12 months.
