In April 2019, astronomers detected a narrow, clean radio signal at 982 MHz from Proxima Centauri, our nearest star at 4.2 light-years away, which was never repeated and remains unexplained despite eliminating all known interference sources.

Our Nearest Star Just Called. We Have No AnswerHinzugefügt:
Our nearest star sent us a signal one time, then went silent forever. [music] In April 2019, the park's telescope detected something it shouldn't have, a radio signal, narrow, clean, stationary, [music] from the direction of Proxima Centuri, 4.2 light years away. The frequency was 982 MHz, [music] exactly the band we would use to make contact. Every satellite was checked.
Every transmitter eliminated. It [music] came from the star. Proxima Centauri hosts a planet inside its habitable zone. [music] The signal was never repeated. No explanation has been confirmed. Right now, that telescope is pointed at the same patch of sky listening and the star is not answering.
