A new generation of ground-based telescopes could be up to 10 times the size of existing instruments and have vision 40 times as sharp as the Hubble space telescope.Astronomers have been hailing the plans, as a European project to build an Extremely Large Telescope (ELT) enters a design testing phase. An ELT is vital if the pace of astronomical breakthroughs is to continue, say experts. The plans were outlined at the UK National Astronomy Meeting in Birmingham. Concepts for ELTs include the Thirty Meter Telescope (TMT) being considered by the US and Canada; and the Euro50 and Overwhelmingly Large Telescope...
