Astronomers don’t have an explanation yet for a beam of radio waves from the direction of the star Proxima Centauri


Nobody believes it was ET phoning, but radio astronomers admit they don’t have an explanation yet for a beam of radio waves that apparently came from the direction of the star Proxima Centauri.

“这是某种技术信号。问题是这是地球技术还是来自远方的技术,”宾夕法尼亚州立大学的研究生索菲亚·谢赫说,她带领一个研究小组研究信号,并试图破解信号的来源。她是由俄罗斯亿万富翁投资者尤里·米尔纳(Yuri Milner)出资1亿美元寻找外星无线电波的“突破倾听”项目的一部分。现在,该项目无意中发现了迄今为止最吸引人的有利条件。

“It’s some sort of technological signal. The question is whether it’s Earth technology or technology from somewhere out yonder,” said Sofia Sheikh, a graduate student at Pennsylvania State University leading a team studying the signal and trying to decipher its origin. She is part of Breakthrough Listen, a $100 million effort funded by Yuri Milner, a Russian billionaire investor, to find alien radio waves. The project has now stumbled on its most intriguing pay dirt yet.


Proxima Centauri is an inviting prospect for “out yonder.”


It is the closest known star to the sun, only 4.24 light-years from Earth, part of a triple-star system known as Alpha Centauri. Proxima has at least two planets, one of which is a rocky world only slightly more massive than Earth that occupies the star’s so-called habitable zone, where temperatures should be conducive to water, the stuff of life, on its surface.


The radio signal itself, detected in spring 2019 and reported on earlier in The Guardian, is in many ways the stuff of dreams for alien hunters. It was a narrow-band signal with a frequency of 982.02 MHz as recorded at the Parkes Observatory in Australia. Nature, whether an exploding star or a geomagnetic storm, tends to broadcast on a wide range of frequencies.
