CANBERRA (Reuters) - Scientists searching the stars for aliens are convinced an E.T. is out there -- it's just that they haven't had the know-how to detect such a being.
But now technological advances have opened the way for scientists to check millions of previously unknown star systems, dramatically increasing the chances of finding intelligent life in outer space in the next 25 years, the world's largest private extraterrestrial agency believes.
"We're looking for needles in the haystack that is our galaxy, but there could be thousands of needles out there," Seth Shostak, the senior astronomer at California's non-profit Search for Extraterrestrial Intelligence (news - web sites) (SETI) Institute, told Reuters in an interview on Tuesday.
"If that's the case, with the number of new star systems we now hope to check, we should find one of those in the next 25 years."
But Shostak, visiting Australia to attend a conference on extraterrestrial research, said detecting alien life, like the big-eyed alien in the film E.T., was only the start.
"Even if we detect life out there, we'll still know nothing about what form of life we have detected and I doubt they'll be able -- or want -- to communicate with us," Shostak said.
Since it was founded in 1984, the SETI Institute has monitored radio signals, hoping to pick up a transmission from outer space. Its Project Phoenix conducts two annual three-week sessions on a radio telescope at Arecibo, Puerto Rico.
Project Phoenix, widely seen as the inspiration for the 1997 film "Contact" starring Jodie Foster [based on the Carl Sagan novel of the same name], which depicted a search for life beyond earth, is the privately funded successor to an original NASA (news - web sites) program that was canceled in 1993 amid much skepticism by the U.S. Congress.
But the search has been slow. About 500 of 1,000 targeted stars have been examined -- and no extraterrestrial transmissions have been detected.
E.T. NOT ON THE LINE
"We do get signals all the time but when checked out they have all been human made...and are not from E.T., more AT&T," said Shostak.
He said the privately-funded institute was developing a giant $26 million telescope to start operating in 2005 that can search the stars for signals at least 100 times faster.
The so-called Allen Telescope Array, named after sponsor and Microsoft co-founder Paul Allen, is a network of more than 350, 20-foot satellite dishes with a collecting area exceeding that of a 338-foot telescope.
The Allen array, to be built at the Hat Creek Observatory about 290 miles northeast of San Francisco, will also expand the institute's stellar reconnaissance to 100,000 or even one million nearby stars, searching 24 hours a day, seven days a week.
Shostak said he is convinced there is intelligent life out there -- but don't expect to find a loveable, boggle-eyed E.T.
He said if any aliens share the same carbon-based organic chemistry as humans, they would probably have a central processing system, eyes, a mouth or two, legs and some form of reproduction.
But Shostak thinks any intelligent extraterrestrial life will have gone light years beyond the intelligence of man.
"What we are more likely to hear will be so far beyond our own level that it might not be biological anymore but some artificial form of life," he said. "Don't expect a blobby, squishy alien to be on the end of the line."

Hmm, what makes him think that all such intelligent ETs would be advanced beyhond humankind. Some might be, others might be much less advanced. We more or less sat on our rumps for many millinia before inventing civilization. Others may still be sitting there.
Besides, I tend to think that these folks are looking in the wrong part of the electromagnetic spectrum. Sort of like looking for signals in the low frequency band (and Morse code like ones at that) when all the talking is going on at microwave and above frequencies. They are also probably looking for the wrong type of modulation.
It is still an assumption isn't it? Or did I miss something?
I know you will never read it in the standard journals or pop science media, but isn't the fact that ET hasn't been discovered yet, something of a mystery, given the assumption that life can form through a purely unguided naturalistic process. If the assumption is true, then life should be plentiful in the universe [arguably even our own galaxy], given the numbers of stars alone.
Awaiting the usual explaining away.
Brian.
Arguably even in our own solar system (Mars, Europa, Ganymede).
I read it. Personally I think the bottleneck is developing technology. It took us long enough. There could be loads of intelligent species out there, but living like ancient Egypt.
