Astronomers have discovered an "intriguing signal" from the closest star system to the Sun

Researchers are still preparing a discovery document and the data has not been released to the public. But the signal is reported to be

is a narrow beam of 980 MHz radio waves,discovered in April and May 2019 with the Parkes Telescope in Australia. The Parkes Telescope is part of the $ 100 million Breakthrough Listen project, which seeks to find radio signals from technological sources outside the solar system. The 980 MHz signal appeared once and was never detected again. This frequency is important because, as Scientific American points out, it is in this band of radio waves that signals from artificial ships and satellites are usually absent.

Breakthrough Listen constantly discoversUnusual Radio Signals - Between terrestrial sources, the sun's natural radio signal, and natural sources outside the solar system, there are many radio waves bouncing around. But this signal appears to have come directly from the Proxima Centauri system, just 4.2 light years from Earth. Even more tempting, the signal reportedly shifted slightly during the observation. It reminded astronomers of the planetary shift. Proxima Centauri has one known rocky planet that resembles Earth and is 17% larger than it.

The Guardian quoted an unnamed source,who has access to data on this signal, who stated: “This is the first serious candidate for alien communication after the Wow signal - a famous radio signal discovered in 1977, which also resembled a signal from an extraterrestrial ship. But the Guardian warns that the signal "is probably also of terrestrial origin."
