Astronomers detect a powerful radio-wave laser

The first hydroxyl megamaser of its kind.

Centaurus A is a giant elliptical active galaxy 12 million light-years away. At its heart lies a black hole with a mass of 55 million suns. This image shows the galaxy at radio wavelengths, revealing vast lobes of plasma that reach far beyond the visible galaxy, which occupies only a small patch at the centre of the image. The dots in the background are not stars, but radio galaxies much like Centaurus A, at far greater distances.

The effect is a consequence of Einstein’s General Theory of Relativity.

This image shows a new view of the Milky Way from the Murchison Widefield Array, with the lowest frequencies in red, middle frequencies in green, and the highest frequencies in blue. Huge golden filaments indicate enormous magnetic fields, supernova remnants are visible as little spherical bubbles, and regions of massive star formation show up in blue. The supermassive black hole at the centre of our galaxy is hidden in the bright white region in the centre. Credit: Dr Natasha Hurley-Walker (ICRAR/Curtin) and the GLEAM Team

Fourteen radio galaxy predictions ClaRAN made during its scan of radio and infrared data. All predictions were made with a high ‘confidence’ level, shown as the number above the detection box. A confidence of 1.00 indicates ClaRAN is extremely confident both that the source detected is a radio galaxy jet system and that it has classified it correctly.
