Decades-long Blinking Radio Signal from Space Baffles Astronomers
TL;DR
Astronomers have discovered a mysterious interstellar radio signal that has been blinking on and off every 22 minutes for over 30 years. The signal, which is repeating and lasts for five minutes with 17-minute gaps, resembles a pulsar but spins 1,000 times slower. The source has been observed since 1988 and is still active, challenging current theories about how neutron stars generate radio waves. While the possibility of extraterrestrial intelligence is tempting, further observations and analysis are needed to solve this cosmic mystery.
