Sun's 'twin' an ideal hunting ground for alien life

Astronomers have found the most Sun-like star yet, and they say it is an ideal place to hunt for alien civilisations.
The star, called HIP 56948, lies a little more than 200 light years from Earth. Its size, mass, temperature, and chemical makeup are all so similar to the Sun's that no measurable differences could be found in high-resolution observations made by the 2.7-metre telescope at the McDonald Observatory in Texas, US.
