Interstellar comet ATLAS gives no signals: new data debunk the myth about aliens.

According to ТСН: The interstellar comet 3I/ATLAS attracted attention due to numerous rumors about the possible presence of alien technologies on its surface. However, recent studies have not revealed any technosignatures, such as radio signals or emissions, that could confirm the existence of advanced technology.

New observations

Since the discovery of the interstellar object 3I/ATLAS on July 1, 2025, there has been a plethora of speculation regarding the possibilities of advanced civilizations existing beyond the Solar System. Recently published results from radio observations conducted at the Green Bank telescope under the Breakthrough Listen program will likely disappoint those who hoped for evidence of such a civilization.

3I/ATLAS - natural or artificial object?

Only two other interstellar objects have previously been spotted in our Solar System. The first, 1I/‘Oumuamua', was initially recognized as an asteroid, then as a comet; the second, 2I/Borisov, is classified as a comet. 3I/ATLAS has characteristics of a comet, yet there have always been speculations about its possible artificial origin. Scientists remain skeptical, actively studying the object and collecting data from various telescopes.

In the six months following its discovery, numerous observations across different wavelengths were conducted, yet the results did not indicate the presence of technosignatures.

Green Bank Observations

Researchers working on the study assert that interstellar probing devices likely utilize narrowband radio signals due to their effectiveness in transmitting information. The search among 471,000 potential signals revealed only nine events, which turned out to be noise. The analysis showed no signs of technosignature from 3I/ATLAS.

The authors of the study state: 'Our study concludes that there are no isotropic continuous wave transmitters greater than 0.1 watts at the location of 3I/ATLAS. In comparison, a mobile phone is approximately an isotropic continuous wave transmitter of about 1 watt.'

The search continues

Data collected during the study and through the Breakthrough Listen program is available to the scientific community, and its collection will continue using various telescopes. New data about 3I/ATLAS is expected to emerge in the future, although the likelihood of detecting technosignatures remains low.

Simultaneously, numerous telescopes will continue to monitor new interstellar objects entering our Solar System, as well as potential technosignatures.

Previously, the comet 3I/ATLAS amazed scientists with its cryovolcanism: powerful eruptions of ice and dust were observed on its surface as it approached the Sun. Studies also suggest that this cosmic object unexpectedly resembles trans-Neptunian objects of the Solar System and primitive chondrite meteorites.

In light of the new results, researchers continue searching for possible signs of life beyond Earth. Despite the absence of evidence for alien technology in the case of 3I/ATLAS, the study of interstellar objects opens new horizons for science and allows for a better understanding of the nature of our Universe.
