The waves were captured during a 30-hour observation, between April and May last year, by the Parkes telescope, in Australia. And they seem to have come from the region where Proxima Centauri is, the closest star to the Solar System, about 4.2 light years away, and where a planet has already been found capable of harboring life. The study carried out in 2020 sought to analyze stellar eruptions. But, as is customary, the data collected continued to be analyzed, to see if there were any signs that could interest SETI, a program in California whose acronym stands for Search for Extraterrestrial Intelligence, or Search for Extraterrestrial Intelligence). In October of this year, the intern responsible for the task arrived at a set of five radio signals, alerting the team of the Breakthrough Listen project (something like Audi\u00e7\u00e3o de Descobertas, in a free translation), connected to SETI. Since then, the researchers of the initiative have made several checks that serve to verify whether the waves captured by the telescope are a natural phenomenon (stars can emit them for example) or some type of interference generated by equipment that are right here on Earth. Another possibility is that they are radio signals emitted by machines that are in space, but were sent by humanity itself, as probes and satellites. Until today, one of these possibilities explained all the signals captured. What makes the new set of signs special is that, after several analyzes, it remained unexplained. This means that, so far, SETI scientists, although they think the possibility is very remote, have not ruled out the possibility that this is the long-awaited "techno-signature", a signal emitted by some technological equipment made by intelligent beings living in another planet. Leaked data The fact that there was still some possibility that it was a signal emitted by aliens ended up leaking to the respected British newspaper The Guardian, which generated an uproar among those waiting for proof that it is not only the Earth that harbors intelligent life. The disclosure of the story prompted Pete Worden, executive director of the Breakthrough Listen Project, to comment on Twitter.\t\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t "The Breakthrough Listen team has detected several unusual signs and is investigating them carefully. These signs are probably interference that we cannot explain. More analysis is being done now," he wrote on the social network. "Read what we said! No one is claiming it is a techno-signature. We are in the process of following established protocols. Right now, we have interesting signs that, we believe, are interference, but which we have not yet been able to pinpoint the origin of. ", added Worden. The Breakthrough Listen Team has detected several unusual signals and is carefully investigating. These signals are likely interference that we cannot fully explain. Further analysis is currently being undertaken- S. Pete Worden (@worden) December 19, 2020 Candidate 1 For a research area that began its search in the late 1970s with no results to date, an inexplicable sign immediately becomes something great. Speaking to Scientific American, researchers linked to the project asked for caution and rejected any hasty conclusions, but explained why the captured signal is so interesting.\t\t\t\t\t\t\t\t\t\t \t\t\t\t\t\t "It has some properties that have passed it (not to be dismissed as a possible alien sign) in several of our checks. We can't explain it yet," said Andrew Siemion, of the University of California at Berkeley. "It is the most exciting signal we have ever encountered on the Breakthrough Listen project, because we have never had a signal passing through so many of our filters," added Sofia Sheikh, a scientist at Penn State University. A clear sign that the set of radio signals is being taken seriously by scientists is the fact that they were given the name BLC1. The acronym stands for Breakthrough Listen Candidate 1, that is, Candidate 1 for Breakthrough Listen.
