This month's target is nearby galaxy NGC 5128，also known as Centaurus A, in the heart of the celestial centaur. The first recorded observation of the galaxy was by Scottish astronomer James Dunlop, who discovered it in 1826 from his observatory in New South Wales, Australia. In 1949, NGC 5128 was determined to be the host of the "Centaurus A" radio source. That discovery was made by a team led by John Gatenby Bolton, who, like James Dunlop a century earlier, was British-born but living and working in Australia.
