Summary
Particles emitting radio waves stream millions of light-years into space from the heart of the galaxy Centaurus A in this picture made by CSIRO. Data for the image was gathered with CSIRO&apos;s Australia Telescope Compact Array and Parkes radio telescope: the frequency of the radio waves was 1.4 GHz. The smallest structure visible in the image is 680 parsecs (210 light-years) across : the scale bar represents 50,000 parsecs (about 163,000 light-years). The white dots are not stars but background radio sources, each a huge galaxy like Centaurus A in the distant universe.</p><p>Image credit: Ilana Feain, Tim Cornwell & Ron Ekers (CSIRO/ATNF).
