Astronomers have spotted what may be the strongest candidate yet for an alien signal. Researchers at the Breakthrough Listen project have found an unusual beam of radio light coming from around our nearest neighbouring star, Proxima Centauri, according to a report in
The Guardian on 18 December.
Any purported discovery of aliens always has to be taken with scepticism. That is especially true in cases where a signal appears to be a possible technosignature, a sign of alien technology rather than simply life beyond Earth. The Breakthrough Listen team has been extremely cautious about this find. “No one is claiming it’s a technosignature,” tweeted Pete Worden, chairman of the Breakthrough Prize Foundation.
