University of Sussex set to discover a new VISTA of the Universe

The University of Sussex will be among the first research institutions to access data from the world's most powerful astronomical survey telescope, whose development has just taken an important step forward.

The Visible and Infrared Survey Telescope for Astronomy (VISTA) project has selected a Russian company to create an extremely accurate surface on the telescope's mirror, using computer-controlled surface-polishing techniques - a process that will take 18 months.

When it is completed in 2006, the 4m-wide VISTA telescope will be the world's largest facility for ground-based astronomical survey work. It will be equipped with the world's largest infrared camera and will enable astronomers to survey the heavens in the infrared to an unprecedented depth, opening up an entire new vista on the Universe.

The telescope is being built at a cost of more than £25m and will become part of the European Southern Observatory's Cerro Paranal Observatory at an altitude of 2,635m, in the Atacama Desert in Chile.

VISTA is financed by the UK's Joint Infrastructure Fund with an additional contribution from the Particle Physics and Astronomy Research Council (PPARC) through a consortium of 18 UK universities including the University of Sussex.

The University's Dr Robert Smith, who is a member of the consortium board, said: "The VISTA telescope will be able to map most of the Southern sky to unprecedented depth. The combination of the size of the mirror and the amount of sky that it can view makes it completely unique, and on that basis it beats all existing or planned telescopes. I anticipate Sussex astronomers being involved in a variety of research collaborations based on its results."

Dr Jon Loveday sits on the consortium's science committee with his colleague Dr Seb Oliver, both from the University of Sussex. Dr Loveday said: "Our membership of the consortium will enable us to access the data from the telescope as soon as it is available and make the best use of it. Sussex will be among the first places to have access to the data it produces."
