Australian astronomers reveal image of a cosmic “blue whale”

Centaurus A, a vast galaxy 14 million light-years distant, holding a gigantic black hole in its center 50 million times larger than the Sun, is emitting a radio glow that covers an area of the sky 200 times larger than the Moon. And not a single part of it is visible to the eye – only radio astronomers even know it exists.
