Radio Galaxy Centaurus A (VIDEO) International Centre for Radio Astronomy Research This video is under embargo. Please login to access this video. Caption A video showing the radio galaxy, Centaurus A, which hosts the closest actively feeding black hole to Earth. The video shows the apparent size of the galaxy at optical, X-ray and submillimetre wavelengths from Earth when compared to the Moon. It then zooms out to show the enormous extent of the surrounding bubbles that are observed at radio wavelengths. Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth. Find out more at: www.icrar.org/centaurus.
