NEW YORK: An artificial intelligence (AI) system designed to identify signs of alien presence in space has made a remarkable discovery, detecting eight potentially significant signals.
International scientists collaborating on the Breakthrough Listen project have harnessed the capabilities of this AI machine.
The initiative focuses on exploring deep space for any potential indications of extraterrestrial life, primarily by scrutinizing radio signals and other potential transmissions that might originate from alien civilizations.
Given the tendency for many signals to be false alarms, researchers have innovatively employed an AI system to expedite the process of scrutinizing these potential signals of alien origin.
The AI operates as an algorithm, sifting through copious amounts of data gathered from radio telescopes. Its objective is to pinpoint signals that exhibit characteristics indicative of an alternative life form’s communication.
The lead researcher, Peter Ma, from the University of Toronto, spearheads the team as part of the Search for Extraterrestrial Intelligence (SETI) program. Their investigation spanned 820 distinct celestial targets and employed the Green Bank Telescope situated in West Virginia.
Published earlier this year in Nature Astronomy, their findings are a result of analysing more than 480 hours of observations.
Within this extensive dataset, the AI system identified eight signals that demonstrated potential promise as signals from extraterrestrial intelligence. These signals had not been previously identified, highlighting the AI’s ability to expand the search parameters.
The team, however, refrained from drawing definitive conclusions about the origins of these signals. Nevertheless, they deemed the research to be a testament to the AI’s efficacy, reinforcing its relevance in SETI efforts.
Expressing their perspective, the team stated, “This machine-learning approach presents itself as a leading solution in accelerating SETI and other transient research into the age of data-driven astronomy.”
Although these findings haven’t yet yielded certainty about the nature of the signals, their discovery has advanced our understanding.
Professor Michael Garrett has noted that the AI system likely focuses on specific attributes, such as narrow signal bands, signal disappearance upon telescope redirection, and Doppler drifting, influenced by the motion of both Earth and the potential extraterrestrial source.
While the eight signals’ definitive origins remain enigmatic, the team encourages further investigations. “We encourage further re-observations of these targets,” they urged.
In essence, whether these signals ultimately turn out to be genuine or not, the AI breakthrough marks a significant stride toward answering one of humanity’s age-old questions: Are we alone in the vast expanse of the universe?
