New search to discover alien life forms
By JOHN von RADOWITZ A NEW search for aliens is to begin which will look
rather than listen for signs of extra-terrestrial intelligence.
All attempts so far at searching for evidence of alien civilisations has
relied on scouring the airwaves for radio messages. But a new venture about
to get under way in America will use optical telescopes to scan the skies
for light signals.
Two optical SETI (Search for Extra Terrestrial Intelligence) projects will
be based at the University of California, Berkeley, and one at the Harvard
University and Smithsonian Observatory in Cambridge, Massachusetts.
Louis Friedman, executive director of the Planetary Society which is
sponsoring the searches, said: ``We have been listening for alien signals
for decades; it's time we started to watch for signals as well.''
One of the Berkeley projects will look for very short pulses of light from
nearby stars similar to the Sun, as well as from a few globular clusters
Using Berkeley's 30-inch automated telescope, it will search for light
pulses as short as a billionth of a second.
The other Berkeley team will look for steady, extremely narrow band laser
The Harvard scientists have built a special detector attached to a 61-inch
optical telescope. It will tap into the light being studied by astronomers
measuring the speed of 2,500 nearby Sun-like stars.
Searching for narrowband laser pulse signals from ETs was first suggested
by Nobel Prize winner Charles Townes.
