In an Australian sheep pasture, Santa Clara County researchers are working day
|
||
|
and night to prepare for the most sweeping search ever for intelligent life
|
||
|
outside the Earth.
|
||
|
|
||
|
Using the huge Parkes radio telescope in New South Wales and truck filled with
|
||
|
Silicon Valley computers, the group from Mountain View's SETI Institute will
|
||
|
begin to listen for cosmic conversation between aliens at 4 p.m. Wednesday,
|
||
|
California time.
|
||
|
|
||
|
Serious science
|
||
|
|
||
|
Although it may sound like something straight out of a supermarket tabloid --
|
||
|
Scientists to Eavesdrop on Aliens! --this is serious stuff, at least 30 years
|
||
|
in the making. The scientists and technicians take pains not to promise too
|
||
|
much in their search for extraterrestrial intelligence, which they abbreviate
|
||
|
as SETI. There are too many unknowns.
|
||
|
|
||
|
But they declare proudly that this search is far more advanced than any to
|
||
|
date.
|
||
|
|
||
|
"We could have success at any step," said SETI physicist John Dreher, "but
|
||
|
we're prepared for the long journey. It might take a decade. It might take a
|
||
|
century."
|
||
|
|
||
|
Even that long wait would be worth it, researchers say, since the earthly
|
||
|
impacts of overhearing an unearthly discussion would be profound.
|
||
|
|
||
|
Would end a lot of conflict
|
||
|
|
||
|
"It would be a historic event that would galvanize humanity into a more
|
||
|
cohesive body," said Barney Oliver, a retired Hewlett-Packare vice president
|
||
|
who has worked with Mountain View's SETI Institute since 1971. "To realize
|
||
|
we're one of many civilizations would create a bond between us here on Earth
|
||
|
and end a lot of social conflict."
|
||
|
|
||
|
During the five-month experiment known as Project Phoenix, scientists will use
|
||
|
the 210-foot-diameter Parkes antenna -- the largest in the southern hemisphere
|
||
|
-- to eavesdrop on sounds in the vicinities of 200 nearby stars. Because the
|
||
|
carefully chosen stars are similar to our sun, they are more likely than most
|
||
|
to have a planet like Earth circling them.
|
||
|
|
||
|
Researchers will listen for signals that intelligent beings may have
|
||
|
intentionally sent our way, said SETI scientist Seth Shostak, or for signals
|
||
|
that may have inadvertently escaped from a distant planet much like " the
|
||
|
sounds of 'I Love Lucy' come off the earth."
|
||
|
|
||
|
28 million radio channels
|
||
|
|
||
|
SETI's high-speed computers, shipped to Australia from Mountain View, will
|
||
|
analyze some 28 million radio channels at once.
|
||
|
|
||
|
"Unfortunately , ET didn't send us a postcard to tell us where on the radio
|
||
|
dial we could find him," Shostak said.
|
||
|
|
||
|
To the SETI computers, an artificially produced extraterrestrial signal would
|
||
|
look much like a lone tree sticking out in a wide field of scrub.
|
||
|
|
||
|
Although searches for cosmic radio signals began 35 years ago, Project Phoenix
|
||
|
uses equipment that can search 28 million channels -- three times as many as
|
||
|
the last search -- said SETI President Frank Drake, who carried out the first
|
||
|
such search in 1960. Plus, scientists can now check out any unusual signal
|
||
|
immediately. Before scientists gathered sounds and analyzed the data later.
|
||
|
|
||
|
"This experiment is thousands to a million times better in the technical sense
|
||
|
than previous experiments have been," Shostak said. "Will we hear something
|
||
|
before the millennium? Yes, I think we will."
|
||
|
|
||
|
Shostak may be one of the more optimistic scientists, but even the National
|
||
|
Academy of Sciences has praised SETI's approach. Project Phoenix is a smaller
|
||
|
version of a 10-year NASA program that was abruptly canceled by Congress in
|
||
|
the fall of 1993 after on senator called it the "great Martian chase." NASA
|
||
|
had spent $60 million on the search, including $30 million on equipment.
|
||
|
|
||
|
But with $4 million in donations from some of the high-tech industry's most
|
||
|
powerful players -- including David Packard and William R. Hewlett, founders
|
||
|
of Hewlett-Packard; Gordon Moore, co-founder and chairman of Intel; and Paul
|
||
|
Allen, Microsoft's co-founder and owner of the Portland Trail Blazers
|
||
|
basketball team -- the non-profit SETI Institute was able to upgrade the NASA
|
||
|
equipment to continue the search.
|
||
|
|
||
|
Researchers plan to complete their 200-star survey at Parkes, a town about 250
|
||
|
miles west of Sydney, in June. It is not easy duty; Shostak notes that Parkes
|
||
|
has one of the highest concentrations anywhere of poisonous snakes and
|
||
|
spiders. After finishing their work there, they will move to radio telescopes
|
||
|
in the northern hemisphere, where they plan to look at 1,000 stars by the year
|
||
|
2000.
|
||
|
|
||
|
In their search for unearthly life, the scientists are motivated as much by
|
||
|
skepticism as optimism. Almost to a person, they do not believe in UFOs.
