Intelligent Signals From Space - SETI Correction
From George Filer <Majorstar@...
Apparently you can't believe every thing you read. Kevin Dalley of SETI
Institute wrote to inform me that I had put out erroneous information
concerning a signal from space. This was somewhat of a shock because, I read
the story in the Home News Tribune (Central New Jersey's Voice since
1879).or at least the copy of it provided to me in Pat Marcatillio's UFO
Meeting at the Hamilton Square Library on December 1, 1999. I even heard
rumors of some kind of contact.
The next day I put out the story, but several readers asked for
confirmation. I went to the Home New Tribune website at www.injersey.com/hnt
November 29, 1999, to find out if the story was true. The entire story is
carried on their website, but is quite a bit longer than the story carried
in the newspaper. They apparently cut the last part of the story to fit it
in the newspaper. It is the truth as far as it goes. Apparently, what
initially had been a strong signal faded. Unfortunately so does the story.
Here's the latest UPDATE ON THE FRONT PAGE STORY that included a nice photo
of ET from the movie. The news paper article cuts off the full Gannett news
release giving the impression that this is a strong signal coming from a
small star HD119850. Apparently, some contact was made for a short while,
but it hasn't continued and this is the key. I guess I too got caught up in
hoping there was real contact.
My newpaper article copy ends at the bottom of A-2 with: "And in a universe
of 50 billion galaxies, each made up of a half trillion stars, the chances
of striking ET gold are radically remote." Apparently the editor cut the
The entire Home News Tribune website article is carried below and goes on to
say what was thought to be a strong signal from space faded away.
Unfortunately the article ending on the bottom of Page A2, in the newspaper
infers that we are getting a strong signal.
Was It A Blip Or A Beacon From The Cosmos?

ARECIBO, Puerto Rico - Call it a close encounter with what promises to be
the most important scientific discovery of all time.

With galaxies such as the Milky Way strewn with Earthlike planets, the
chances of hearing from someone like E.T. -- shown here in a still from the
1982 film -- may not be too bad.
Midway through the midnight shift at the world's largest radio telescope,
astronomer Jill Tarter picked up what appeared to be a signal coming from a
small star named HD119850.
There was no mistake. The beacon came in loud and clear at 1535-MHz on the
telescope's radio dial.
Yet it matched nothing in the computer's database of known terrestrial
noise: cellular telephones, pagers, radars and satellites that often
masquerade as broadcasts from alien beings.
What's more, a backup telescope in England was hearing the same beacon -- a
clear sign the signal was not salsa music from a San Juan radio station
bouncing back off the atmosphere.
Tarter, the real-life inspiration for the character played by actress Jodie
Foster in the movie "Contact," took immediate notice and a long drink from
an oversized coffee mug.
Snapping to attention in her wheeled office chair, she rolled over to a
computer and tapped at its keyboard. Then her voice, almost giddy, rose in
"You may be here for something important," she said.
As the 21st century approaches, pioneering researchers are uncovering signs
that suggest primitive life may be abundant in the universe. But Tarter and
her colleagues are after much bigger game: proof that intelligent life
exists elsewhere in the cosmos.
Tarter, 55, is chief scientist with the SETI Institute of Mountain View,
Calif., a nonprofit, privately financed group that carries out a Search for
Scientific vagabonds, the institute's two dozen astronomers and computer
engineers have no permanent home base other than some suburban office suites
near San Francisco. Their meager budget goes to buying telescope time at
Located high atop a mountain, the heart of the observatory is a massive
aluminum dish that covers 20 acres. Radio signals bounce off the dish and
into a 900-ton instrument carrier suspended by steel cables above it.
The equipment works like a giant ear, enabling SETI scientists to listen for
radio signals from faraway stars. The premise is that those stars could
harbor the planetary homes of intelligent civilizations.
The signal that got Tarter's attention came from a star 106 trillion miles
away from the Arecibo control room, a bland computer lab with off-white
walls and worn linoleum floors.
All the "listening" is done by computers that scan 28 million radio channels
in search of unmistakable, repetitive artificial signals from other solar
The problem is distinguishing what could be an alien call from the growing
cacophony of terrestrial noise. An increasing gaggle of satellites above
Earth swamp the airwaves with signals for cell phone conversations and TV
programs. Radio stations broadcast constantly, and military and civilian
radars scan the skies for enemy intruders and commercial airliners.
Here's how it's done: Should a promising signal pop up, SETI computers first
compare the beacon to a catalog of known local noise. Any signal that
matches is discarded automatically. But if the beacon is unfamiliar, a
second radio telescope at Jodrell Bank near Manchester, England, swings into
If Manchester radio telescope doesn't detect the suspect signal, then the
beacon isn't coming from a distant star: It's local Puerto Rican noise that
hasn't been catalogued.
But if the signal is strong enough to be picked up thousands of miles away
in England, too, then the beacon is put to another test.
An alien signal truly coming from a distant star would arrive in the United
Kingdom at a slightly different frequency than it would in Puerto Rico. It
also would drift just a bit on the radio dial.
That's because Earth is rotating, and the telescopes in Puerto Rico and
England are widely separated.
Those subtle differences are predictable enough to be calculated with great
precision, providing a mathematical way to make certain that Earthly jabber
isn't mistaken for a message from afar.
The suspicious beacon that startled Tarter passed the first two alien signal
tests. On cue, the huge Arecibo telescope automatically began to swing a few
degrees, pointing not at HD119850 but at blank sky, in yet another test.
A true signal from ET would disappear, a result of the telescope being aimed
away from the target star. But if it persisted, then it couldn't be coming
from the far-off star because the telescope no longer was pointed at it. It
would have to be local interference.
This time, it vanished.
And when the British telescope nodded away from the target, the beacon
disappeared there, too. Maybe, just maybe, Tarter was on to a most
But as the telescope ground its gears, the pragmatic Tarter immediately
started to discount the possibility of making contact.
After all, the star is only one of 1,000 being scrutinized by SETI
scientists. And in a universe of 50 billion galaxies, each made up of a
half-trillion stars, the chances of striking ET gold are radically remote.

In fact, the prospects for success are so slim that people often wonder why
serious astronomers would devote entire careers to such a pursuit.
"Some people would say it's nutty to toil your whole life and never see the
results, and that's a distinct possibility here," admitted SETI scientist
Seth Shostak, 56. But "think of the enormous payoff. I mean, this is the
purest longshot horse in science today. But if we succeed, it's really big.
So you accept the low odds."
Tarter, too, knows the needle-in-the-haystack nature of the search, and as
the Arecibo telescope locked back on to HD119850, she stared intensely at
the 19-inch computer screen before her.
But SETI computers decided the signal had not been the real thing. That was
it. The show was over.
Outside, the grinding of telescope gears meant the computers were moving on
to the next star on a preprogrammed target list.
Tarter slumped back in her chair, a bit deflated.
What initially had been a strong signal, she said, had faded. If aliens were
phoning, the volume on the telephone here on Earth wasn't high enough to
hear the second ring.
"Maybe that was E.T. shouting once and never again," she said.

Unfortunately, you have incorrect information on your web site
about the discovery of an
The SETI Institute did not find an intelligent signal. We did look at
HD119850 during this observing run. Other than that, many parts of this
report are accurate.
The SETI Institute did observe HD119850 from Arecibo, on March 20, 21, 22,
23, 26, and April 4. There were a 4 times where we looked for a signal away
from the target star, followed by an on target observation. The signals were
not confirmed in the on target followups.
At Arecibo and Jodrell Bank, there is a significant amount of interference
and it is common to have off source and on source confirmations. While a
real signal would go through the same process, these off source and on
source confirmations are not really unusual enough to be considered
We also observed HD119850 from Green Bank's 140 foot antenna, with Woodbury
as a backup. These observations were made during June, 1997, and January and
March, 1998. Nothing was observed during these observations either.
Jill Tarter's title is actually Director, SETI Research. I believe that her
age is incorrect as well.
HD119805 is an M class star, so the fake article is correct that it is a
Note that the purported news story does not state the report as fact, but
claims that Gannett News Service reported the signal. I have been unable to
locate an initial report from Gannett. I doubt that there is such a report.
By the way, if the SETI Institute had discovered a signal, our bottle of
champagne would be consumed. The unopened bottle is further evidence that
the report of the signal is a hoax.
When we find a signal, it will be announced as soon as we have confirmed it.
Judging from past experience with false alarms, the press will probably know
about the signal within 24 hours of our discovery, whether or not we have
confirmed the signal. Secrecy is impossible in this business.

I guess you can't believe everything you read. I apologize if there was any
inconvenience caused by my article. Next time I'm checking with SETI before
I run this type of article. Thanks Kevin Dalley at the SETI Institute for
correcting my article.
