3C 273

Apart from a couple of quite bright galaxies at right, this area of the night sky in the constellation Virgo looks fairly unremarkable. But at centre, indistinguishable from a star visually, lies the first quasar to have been discovered, 3C 273. The stars in the image are typically some hundreds of light years from the Solar System, and the bright galaxies millions of light years distant, but 3C 273 lies at the immense distance of more than two billion light years.
