Summary
6 March 2012
A major research programme has been launched for 'citizen scientists' to search for signs of intelligent life on other planets. Researchers in California are looking for people to help sort through the vast array of radio signals coming from the skies. There's so much data that professional astronomers don't have enough computer power - or manpower - to analyse it all.

Report
Scientists have been looking for evidence of life beyond earth for decades. They haven't found it yet, but researchers at the SETI Institute, which stands for Search for Extraterrestrial Intelligence, say the skies are so crowded with radio signals, that the clues may be missed.
The telescopes are focusing on more than 150,000 stars but the scientists say they need help to analyse the information that's coming back to earth. They've created a new public web site to allow volunteers to receive the data on their computers.
There could be signs of life and the vital clues that may eventually help scientists answer that age-old question: Are we alone? Professional astronomers will be working with the volunteers to help them understand what they're seeing. And it could be a citizen scientist who spots the first tantalizing signal, proof that life exists beyond the earth.
