This composite image compares the radio glow of an enormous galaxy called Centaurus A to a full Moon.
The white dots in the sky are not stars but other sources of radio emissions that are smaller, or more distant than Centaurus A.
The foreground antennas are the Australia Telescope Compact Array , which captured the radio data used to make up the image.
