I liked this entry too, about the Wow! radio signal from 1977.
The Wow! signal lasted for 72 seconds and was extremely bright:
There has been widespread speculation that the Wow! signal may have been aliens trying to communicate with humans.![👽]()
It turns out, however, that the Wow! signal was a gamma ray burst, probably from a magnetar, whose gamma ray jet passed through a cloud of neutral hydrogen, triggering the signal.
