Jakarta, CNBC Indonesia – Astronomers found 8 suspicious radio signals that they thought were evidence of extraterrestrial technological life.
A team of experts led by University of Toronto student Peter Ma, developed an artificial intelligence algorithm (Artificial Intelligence/AI) new technology that helped them detect signals during an inspection of 820 stars at the Green Bank Telescope in West Virginia.
The AI algorithm uses machine learning to distinguish human-induced signals, such as GPS and cellphone signals, from alien signals from outer space. In previous observations, 8 suspicious radio signals were not detected due to interference. However, after trying again, new signals appear.
Reported from New York Post, Monday (20/2/2023), these 8 signals are not certain proof of the existence of extraterrestrial life. Although the character of these signals is unknown, further studies are needed to arrive at these conclusions.
One of the scientists on the project, Steve Croft, unveiled the main challenge of identifying extraterrestrial life from signals. First, there was such a huge signal stack that it was difficult to find transmissions from foreign worlds.
“Most of the signals detected by our telescopes come from our own technology,” he explained.
Croft stated that the 8 signals could originate from extraterrestrial sources because they are composed of narrow bands (narrowband). Human-induced signals, on the other hand, tend to be broadband (broadband).
In addition, the signal has a slope. This means that the place of origin is likely to have an acceleration relative to the antenna and is most likely not from Earth.
“These signals appear when we look at the stars and disappear when we look away, as opposed to local interference which is generally always present,” said Croft. “Signal [juga] changing its frequency from time to time in such a way as to make it appear far from the telescope.”
