The universe is awash with strange radio signals, but astronomers have now detected a really bizarre one that repeats every hour, cycling through three different states. While they have some ideas about its origin it can’t be explained by our current understanding of physics.
Did we ever figure out what the WOW signal was?
Apparently not yet, astronomers are still waiting for the signal to repeat to appropriately study it.
For now there are just guesses. If such burst isn’t a fluke and repeats, astronomers will get a chance to better study it and provide a confident explanation.
