More than sixty years ago, the search for intelligence began outside the planet (SETI) officially with the Ozma project at the GreenBank Observatory in the West Bank, Virginia. Under the leadership of the famous astronomer Frank Drake (who drafted the Drake equation), this survey used a 25-meter (82-feet) dish to monitor Epsilon Erdiani and Tau City-Najman-similar to the nearby sun-April and July of 1960.

While no conclusive evidence was found indicating an advanced civilization, there were many cases that scientists were unable to exclude this possibility. in Modern paperThe veteran NASA world describes Richard E, as indicated. This poll revealed rapid identical impulses from a sun -like star about 100 light years from Earth, which coincides with similar pulses from a different star observed four years ago.
Dr. Stanton is an inventor of the NASA’s jetpacker, whose work involved in Voyager missions and works as an engineering director of Gravity Recovery and Climate Experience. Since his retirement, he devoted himself to searching for intelligence outside the planet (SETI) using a 76.2 cm (30 inches) telescope at the Shay Meadow Observatory in Big Bear, California, and a multi -channel photo scale designed. The paper, which describes the results of its survey, appeared in the ACTA journal ACTA.
For years, Stanton used these tools to monitor more than 1,300 sunscreen for SETI visual signs. Unlike the traditional Seti surveys that used radio antennas to search for evidence of possible external transfers, Seti visual SETI is looking for a pulses of light that can result from laser connections or guided power sects. This last example has been seen in recent years thanks to the Project Starshot, and to push the energy directed at NASA to the concept of exploration among the stars (Deep-in), and the concepts of task between similar stars.
As Stanton explained, Seti visual field tracks its roots to the 1961 study conducted by Schwartz and the country. They have caused the best way to intelligence outside the planet Earth (ETI) can send a visual signal that surpasses their star with an intense second nano laser pulses.
Since Stanton relates to Universe today via email, its SETI search is different from traditional visual surveys:
“Critics are to stare in one star for about an hour by using the photon to taste the star’s light in what is considered a high degree of time for astronomy (100 samples of microscopic sample). Then the time chain caused by the impulses and visual colors is searched. Any discovery of similar pulses.”
After years of research, Stanton reported unexpected “signal” when observing HD 89389, which is the F-Type star a little brighter and more large than our sun, located in the main constellation of Urs. According to the Stanton paper, this signal consisted of a quick and identical impulsive 4.4 seconds that were not disclosed in previous searches. Then he managed comparisons against signs produced by aircraft, satellites, nikiyat, lightning, glamor in the atmosphere, system noise, etc.
As he explained, I made several things about the discovered legumes about HD89389 unique than anything previously seen:
A. The star becomes brighter, then returns to its ocean level, all in about 0.2 seconds. This difference is very strong that it does not cause random noise or atmospheric disorder. How to make a star, more than a million kilometers away, partially disappear in the tenth of the second? The source of this difference cannot be as the star itself.
for. In all three events, identical impulses are seen mainly, separated between 1.2 and 4.4 seconds (the third event, on a note on January 18 this year, not included in the paper). In more than 1500 hours of research, no single pulse that resembles it was discovered.
C. The exact structure is repeated in the light of the star between almost almost the top of the first pulse in the second pulse 4.4s after that. Nobody knows how to explain this behavior.
D. Nothing was revealed near the star in simultaneous photography or in the background sensor, which easily discovers remote satellites moving near the target star. Common signals of aircraft, satellites, emerging shapes, birds, etc., are completely different from these impulses.
Re-examining the historical data of similar signals revealed another pair of legumes discovered about HD 217014 (51 PEGASI) in 2021. This main star G-Type is located about 50.6 light-years from Earth and is similar to size, mass and age with our sun. In 1995, astronomers at Observatoire de Haute-Proving discovered by the external planets that revolve around this star, a giant of the named Dimidium Since then. This was one of the first external planets to be discovered at all, and the first time that an external planet was discovered around the main sequence star.
At that time, Stanton said, the indication was rejected as a wrong positive resulting from birds. However, the detailed analysis of this possibility was excluded for all the observed pulses. Other possibilities that Stanton explores the Earth’s atmosphere, and perhaps because of the shock wave. However, shock waves are unlikely with perfect timing to coincide with both visual impulses. Other possibilities include stars light with a remote body in the solar system, partial eclipse caused by terrestrial satellites or remote asteroids, and “edge bonds” by a straight edge (as shown in the effect of Sompeld).
There is also the possibility that the gravitational wave has been born these legumes, which requires an additional study. Another interesting possibility is that it can be the result of ETI. As Stanton explained, that is, what has been modified, the light of these stars should be relatively close to Earth, which implicitly means that any ETI activity should be within our solar system. However, Stanton confirms that more data is needed.
“None of these interpretations is really satisfactory at this stage,” he said. “We do not know the type of an object that can produce these impulses or to what extent does it keep them. We do not know whether the dual -pulse sign is produced by something that passes between us and the star or if it is created by something that adjusts the star’s light without moving across the field. Until we learn more, we cannot even say whether or not external properties!”
There are many examples of SETI Optical (OSETI) or Laserseti, including the cooperative effort launched by Breakthrough BehindHrough Gaw that Breakthrough and the collaboration of the Veritas. However, Stanton’s method offers many opportunities to make future SETI surveys, which can search for similar examples of visual impulses. To this end, approaches suggest that they can reveal more about this phenomenon and help astronomers to place more strict restrictions on their potential causes:
“Look for events that use the synchronous optical telescopes. If the object moves between the star and the tubes, this approach should tell us how quickly its transition naturally to the sight line, and its size and distance may be. For differences in the time of light from the star to each telescope.
