The signal from the star, that has roughly the same age, mass and metal composition as the Sun.
Paul Gilster, author of the Centauri Dreams website, said:
“No one is claiming that this is the work of an extraterrestrial civilisation. But the signal is provocative enough that the RATAN–600 researchers are calling for permanent monitoring of this target.”
Seth Shostak, a senior astronomer at the SETI Institute, who wasn’t involved in the signal’s initial detection, said:
“We looked last night with (the) Allen Telescope Array (ATA) last night and didn’t find anything. But like all SETI experiments, you can’t prove it’s not there, only that it is there by finding the signal again.”
