Prof Stephen Hawking backs venture to listen for aliens

Prof Stephen Hawking has launched a new effort to answer the question of whether there is life elsewhere in space.

The £64m ($100m) initiative is said to be the biggest yet in support of the search for extra-terrestrial intelligence.

The 10-year effort will listen for broadcast signals from a million of the stars closest to Earth.
