Astronomers released this week a picture containing more than one billion stars in the Milky Way galaxy. It combines data from two near-infrared1 telescopes – the UK Infrared Telescope (UKIRT) in Hawaii and the VISTA telescope in Chile – and is the result of a decade-long collaboration by astronomers at the University of Edinburgh and the University of Cambridge to process, archive and publish the prodigious quantities of sky survey data generated by these two telescopes.

Dr Phil Lucas from the University of Hertfordshire leads the UKIRT study of the Milky Way, and co-leads the VISTA study. He said: “The combined data on over a billion stars represent a scientific legacy that will be exploited for decades in many different ways. They provide a three-dimensional view of the structure of our spiral galaxy, the Milky Way, while also mapping several hundred nebulae where stars are being born. The VISTA data, in particular, is breaking new ground by showing how several hundred million stars vary in brightness over time.”
