In 2022, astronomers detected a mysterious radio signal coming from deep space. It repeated like clockwork every 18 minutes for several months, something that should not happen, since no known celestial object behaves that way. Then, just as suddenly as it appeared, it stopped. Scientists still do not know what caused it.
My Take: Either this was some unknown space phenomenon, or it was aliens trying to contact us and giving up when no one answered. Either way, I want to know what it was.
