A powerful signal has been spotted coming from the vicinity of a sunlike star, and now astronomers are trying to figure out what it means.

In May 2015, researchers using a radio telescope in Russia detected a candidate SETI (search for extraterrestrial intelligence) signal that seems to originate from HD 164595, a star system that lies about 94 light-years from Earth, the website Centauri Dreams reported over the weekend.

The astronomers have not yet published a study about the detection; they plan to discuss it next month at the 67th International Astronautical Congress (IAC) in Guadalajara, Mexico, according to Centauri Dreams' Paul Gilster, who wrote that one of the team members forwarded him the IAC presentation.
