A strange signal originally thought to have potentially come from aliens might actually have emerged from somewhere else entirely.
Rather than being a telegram from a distant alien civilisation, the message that scientists got excited about earlier this week probably came from “terrestrial disturbance”, researchers close to the team that found the event told the Russian state news agency TASS.
Last week, some scientists searching for life out in space said that they had found a signal that was up to 10 times brighter than the one they’d normally expect. It came from deep in space, and scientists hoped that it might have been sent by another developed civilisation.
But people working close to the discovery have now looked to calm down that speculation – arguing that it’s just as likely that the message came from something on Earth, or near it.
"Last and this year, the telescope’s work has focused on searching for sun-like stars," said telescope researcher Yulia Sotnikova.
"There have been no scientific results within the framework of this research so far. Some time ago, in the spring of this year, an unusual signal was received but its analysis showed that it was most likely a terrestrial disturbance.”
The observatory where the signal was first received is preparing an official disclaimer aimed at calming down reports that the message came from an alien civilisation.
Some scientists working on the Seti project to find life on other worlds had already looked to shoot down the findings – which were brought to light through a blog, and hadn’t been especially well publicised by the scientists themselves. Sceptics said that there was no reason to think that the message was genuinely a signal, not least because it had only been heard once and thus doesn’t meet even the minimum criterion for getting excited about.
It wouldn't be the first time that scientists have thought they have heard a message from aliens only to have it turn out to be wrong. Last year it emerged that astronomers thought they might have received a message from aliens – later discovering that it was actually interference from their microwave.
Russian astronomers have been excited by signals that turned out to be far more earthly than expected in the past, the director of the Institute of Astronomy at the Russian Academy of Sciences, Alexander Ipatov, told TASS. During the soviet period he had been part of a team that got excited by a potential message – only to find that it was in fact a little more dull.
"We, indeed, discovered an unusual signal,” Ipatov told the agency. “However, an additional check showed that it was emanating from a Soviet military satellite, which had not been entered into any of the catalogs of celestial bodies.”
