(NPR) If it were a phone call, we might call it a butt-dial: A strong radio signal that set off questions about whether it emanated from an advanced alien race earlier this week is now believed to have come from a terrestrial source, and possibly from a Russian military satellite.
The clarification came after researchers at the SETI Institute — the private organization that searches for signals that might confirm extraterrestrial life — announced they were investigating an “interesting” radio signal that was reported by Russian astronomers, as Camila wrote for the Two-Way on Tuesday.
But Camila also noted that some experts were warning the signal might be merely interference, and possibly military in origin — and it now seems that that’s the case.
