This illustration shows what the activities of a Kardashev Type III civilisation might look like - encapsulating the energy of stars by so-called Dyson spheres is one way to harness enormous energies on galactic scales; the resulting waste heat products should be detectable by telescopes.

This MWA image shows Centaurus A at radio wavelengths, revealing vast lobes of plasma that reach far beyond the visible galaxy, which occupies only a small patch at the center of the image. The dots in the background are not stars, but radio galaxies much like Centaurus A, at far greater distances.

Evidence for the biggest black hole eruption seen in the Universe comes from a combination of X-ray data from Chandra and XMM-Newton, and the Murchison Widefield Array and Giant Metrewave Telescope, as shown here. The eruption is generated by a black hole located in the central galaxy of the Ophiuchus galaxy cluster, which has blasted out jets and carved a large cavity in the surrounding hot gas.

These are the 27 newly-discovered supernova remnants. The MWA radio images trace the edges of the explosions as they continue their ongoing expansion into interstellar space. Some are huge, larger than the full Moon, and others are small and hard to spot in the complexity of the Milky Way. Image credit: Natasha Hurley-Walker, ICRAR & Curtin / GLEAM Team.
