UK astronomers to co-ordinate their search for alien signals

British scientists are to make a concerted effort to look for alien life among the stars.

Academics from 11 institutions have set up a network to co-ordinate their Search forExtra-Terrestrial Intelligence (Seti).

The English Astronomer Royal, Sir Martin Rees, will act as patron.

The group is asking funding agencies for a small - about £1m a year - sum of money to support listening time on radio telescopes and for data analysis.It would also help pay for research that considered new ways to try to find aliens. Currently, most Seti work is done in the US and is funded largely through private donation.

UK Seti Research Network (UKSRN) co-ordinator Alan Penny said there was important expertise in Britain keen to play its part.

"If we had one part in 200 - half a percent of the money that goes into astronomy at the moment - we could make an amazing difference. We would become comparable with the American effort," the University of St Andrews researcher told BBC News.

"I don't know whether [aliens] are out there, but I'm desperate to find out. It's quite possible that we're alone in the Universe. And think about the implications of that: if we're alone in the Universe then the whole purpose in the Universe is in us. If we're not alone, that's interesting in a very different way."

The scientists believe it is time UK effort was properly co-ordinated

The UKSRN held its first get-together at this week's National Astronomy Meeting.

British researchers and facilities have had occasional involvement in Seti projects down the years. The most significant was the use in 1998-2003 of Jodrell bank, and its 76m Lovell radio telescope, in Project Phoenix. This was a search for signals from about 1,000 nearby stars. Organised - and paid for - by the Seti Institute in California, it ultimately found nothing.

Jodrell has since been updated, linking it via fibre optics into a 217km-long array with six other telescopes across England. Known as eMerlin, this system would be a far more powerful tool to scan the skies for alien transmissions.And Jodrell's Tim O'Brien said Seti work could be done quite easily without disturbin mainstream science on the array.

"You could do serendipitous searches. So if the telescopes were studying quasars, for example, we could piggy-back off that and analyse the data to look for a different type of signal - not the natural astrophysical signal that the quasar astronomer was interested in, but something in the noise that one might imagine could be associated with aliens. This approach would get you Seti research almost for free," the Jodrell associate director explained.

"There are billions of planets out there. It would be remiss of us not to at least have half an ear open to any signals that might be being sent to us."
