SETI breakthrough! NASA scientist discovers three repeating ET signals coming from nearby stars! [19:57]

Maybe it’s an interstellar angler fish blinking to see if another fish is dumb enough to answer and get eaten.

I advise not answering. At best, it’s the alien equivalent of an unsolicited person knocking on your door or calling your cell phone. It might be a good thing, but probably not.

It’s usually just a waste of time and sometimes dangerous. Ergo, I don’t answer the door.

There is little to benefit and much to lose.

Twinkle, twinkle, little star.

Hmmm...
I’m betting that funding is running out and this is the usual BS campaign to restore or increase it...

It is all about money.

SETI and NASA are fighting for their lives—to save their budgets.

People under duress cannot be trusted.

yeah my mistake sorry

YIKES !!! Put that on a giant TV Screen or IMAX...

That’ll scramble your Brain via your Eyes.🤪

Condolences for Your loss. I’m sure He would’ve loved it.🙏

Quite a piece of Tail She is !

Good question.

So if I read this correctly they are detecting repeating pulses of coherent light. I’m not sure that coherent light occurs naturally.

I don't think there are any known "natural" processes that produce coherent light, but maybe there is such a process.

The "1-4-5" chord progression doesn't occur naturally, that's for sure.

Ping me when they are transmitting prime numbers...and transporter plans on the sub harmonic.

You been readin' my book?

Yeah, why did it take until the fifth comment?

For decades, scientific projects like SETI have been looking for evidence of extraterrestrial civilizations. But now, we have learned that perhaps they've been looking for the wrong thing. Since the beginning, SETI has concluded—or at least some scientists at SETI have believed—that the most likely way that extraterrestrial civilizations would communicate with one another is by utilizing the same technologies that we use; that is to say, narrowband radio transmissions.

However, in February of this year, NASA received a laser message from a spacecraft in deep space spanning 16 million kilometers. This signal did not originate from an extraterrestrial civilization or an alien spacecraft, but from a NASA spacecraft on its way to the asteroid belt called Psyche. Unlike traditional radio signals, this transmission came from advanced technology called the Deep Space Optical Communications experiment, or DSOC, which utilizes near-infrared lasers to send data at speeds 10 to 100 times faster than conventional methods NASA has used in the past.

So of course, it has occurred to SETI—and organizations like them—that alien civilizations might use a similar technology to transmit information, as opposed to using outdated radio communications. Thus was born Optical SETI. After an extensive survey of the sky—well, one of several—a particular survey has turned up something quite fascinating: a repeating signal, not from one star but two, signals that have completely defied all natural explanation and may finally be definitive evidence that we are not alone in the universe.

Good afternoon, alien enthusiasts, and welcome to another Angry Alien Bulletin. For decades, the entire philosophy behind SETI’s search for extraterrestrial intelligence—when they have the money to invest in these sorts of searches—is to look for radio signals: narrow beam, powerful radio signals that tend to come only from artificial sources, and also to look for those radio signals on specific frequencies that relate to scientific principles any intelligent species would understand.

For example, the radio frequency associated with hydrogen—the so-called hydrogen line. This, of course, is something any intelligent civilization would understand because hydrogen is the most common element in the universe. Or perhaps a frequency associated with the hydrogen line times pi—both concepts that any civilization would recognize. Or perhaps the square root of the hydrogen line—something understandable to any civilization that understands the basics of the universe and mathematics.

But still, there's no guarantee that intelligent civilizations would use radio frequencies to communicate. It makes sense to us, but is it the medium every civilization would use? Might there be other alternatives? This is what a specific project associated with SETI, known as Optical SETI, decided to pursue—to look for potential laser communications throughout the cosmos.

As a matter of fact, we humans are now using lasers to transfer information over vast distances. Our current probe heading to the asteroid belt has been testing this technology, and so far, it's working very well. However, to communicate information over enormous distances—light years and light years—you would need incredibly powerful lasers that can outshine suns. Not only that, these lasers would have to be very specifically targeted if, say, you wanted to send a communication from a distant star 50 light years away to Earth. The aliens would have to be precisely on target because it would take 50 years for the signal to get here, and it would need to be a very narrow beam laser.

That means accounting for the movement of our solar system, Earth’s orbit around the sun, and so on. A wider beam would require an enormous amount of energy—more power than all of human civilization can generate—to produce a laser that powerful. So, really, Optical SETI has been looking for two things: a laser-like beam of light, or just an extremely bright burst of light that can outshine a star but only lasts a few seconds. Natural events like supernovae or brightening stars last for days or weeks, not just a few seconds.

In addition, they want the signal to repeat. That’s been a frustrating requirement of SETI: to confirm the artificial or intelligent origin of a signal, it has to repeat. Well, just recently—a few weeks ago—a paper came out from Optical SETI confirming that they had indeed found something just like that.

The paper concerns the results of a multi-year survey of more than 1,300 sunlike stars for Optical SETI signals. Veteran NASA scientist Richard A. Stanton was behind this project. Dr. Stanton is a veteran of NASA’s Jet Propulsion Laboratory, with work including the Voyager missions and serving as engineering manager of the Gravity Recovery and Climate Experiment (GRACE) mission. Since retiring, he has dedicated himself to the search for extraterrestrial intelligence using the 76.2 cm telescope at the Shea Meadow Observatory in Big Bear, California, and a multi-channel photometer that he designed.

For years, Stanton has used these instruments to observe over 1,300 sunlike stars for Optical SETI signals. Optical SETI looks for pulses of light that could result from laser communications or directed energy arrays—such as Project Starshot—which will use high-energy lasers to push probes or laser sails to speeds approaching the speed of light. This study traces its roots to a 1961 study by Dr. Schwarz and Townes, who reasoned that the best way an extraterrestrial intelligence could send an optical signal that outshone their star would be with intense nanosecond laser pulses.

Other Optical SETI searches look for signals in infrared wavelengths, high-resolution spectra, or visible light. As Stanton explained to Universe Today via email, his search differs from conventional optical surveys. He said, “My approach is to stare at a single star for roughly one hour using photon counting to sample the star’s light at what is considered a very high time resolution for astronomy: 100 microsecond samples.” The resulting time series are then searched for pulses and optical tones. The instrument uses readily available off-the-shelf components assembled into PC-based systems.

After years of searching, Stanton noticed an unexpected signal on May 14th, 2023, while observing star HD 89389, an F-Type star slightly brighter and more massive than our Sun, located in the constellation Ursa Major (the Big Dipper). According to Stanton’s paper, this signal consisted of two fast, identical pulses 4.4 seconds apart that had not appeared in previous searches. He ran comparisons against signals produced by airplanes, satellites, meteors, lightning, atmospheric scintillation, system noise, and other mundane explanations.

Several things about the pulses made them unique. First, the star gets brighter and fainter and brighter again, returning to ambient levels in about 2 seconds. This variation is too strong to be caused by random noise or atmospheric turbulence. How do you make a star over a million kilometers across partially disappear in a tenth of a second? The source of this variation can’t be as far away as the star itself.

Second, in all three events, two essentially identical pulses are seen, separated by 1.2 to 4.4 seconds. A third event, observed on January 18th of this year, was not included in the paper but adds even more fascinating data. In over 1,500 hours of searching, no similar pulse has ever been detected. Third, the fine structure in the star’s light between the peaks of the first pulse repeats almost exactly in the second pulse. No one knows how to explain this behavior. Fourth, nothing was detected moving near the star in simultaneous photography or background sensors that detect distant satellites.

Common signals from airplanes, satellites, meteors, birds, etc., are all completely different from these pulses. An F-class star like this is bigger and hotter than our G-class sun and located about 100 light years away—a promising area to look for an intelligent civilization. Stanton decided to re-examine historical data for similar signals—and found another pair of pulses detected around star HD 217014 (51 Pegasi) on September 30th, 2019.

This is a much closer, main sequence G-type star, almost identical to our sun and located about 50.6 light years away. In 1995, astronomers detected an exoplanet orbiting this star—a hot gas giant named Dimidium. This was one of the first exoplanets ever discovered and the first around a main sequence star. And where there’s one planet, there’s probably more. At the time, the signal was dismissed as a false positive caused by birds. However, a detailed analysis ruled out this possibility.

Other possibilities Stanton explored included refraction from Earth’s atmosphere, possibly due to a shock wave—highly unlikely, as shock waves would need perfect timing across three pulses. Identical optical pulses from identical shock waves in the atmosphere? Not likely. Other theories include starlight diffraction by a distant solar system body, partial eclipses by satellites or asteroids, edge diffraction (Somerfeld effect), or even gravity waves—though these are poorly understood and require more consideration.

Another interesting possibility—amazing to hear from mainstream scientists—is that it could be the result of extraterrestrial intelligence. As Stanton indicated, whatever modulated these stars' light must be relatively close to Earth, suggesting any ETI activity is within our solar system. Moreover, similar pulses have since been observed from another sunlike star 81 light years away: HD 12051, in January 2025.

To explain all three occurrences, Stanton stresses more data is needed: “None of these explanations are really satisfying. We don’t know what kind of object could produce these pulses or how far away it is. We don’t know if the two-pulse signal is produced by something passing between us and the star, or if it originates closer to the observatory itself.”

It does when you listen to the MC5.

Yep.

How convenient.
