The Centaurus A galaxy


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'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.
