SUMMARY: Astronomers have directly observed a hot disc of dust and gas surrounding a protostar using the twin W.M. Keck telescopes in Hawaii. This is the first published science observation using a technology called interferometry, which combines the light from several telescopes to act as a larger observatory - the twin 10-metre Keck telescopes act as a virtual 85 metre telescope. The observation was of DG Tau, a T-Tauri object which is so young its centre star hasn't begun burning hydrogen; it's surrounded by a disc of dust and gas that could form planets.
