Astronomers have detected an unusual radio signal originating from a star system roughly 40 light-years away, prompting a new round of follow-up observations.
Researchers involved in the discovery caution that natural explanations, including stellar activity, remain the most likely source.
The signal was first flagged by an automated detection system before being confirmed independently by a second observatory.
A peer-reviewed analysis of the findings is expected within the coming months as additional data is collected.
