38. Aliens on the Radio #Wow, via Big Ear

39 years ago, a radio telescope called Big Ear in Ohio received a sudden burst of waves that were most likely from a source near Sagittarius. The signal, called the Wow signal, named after astronomer Jerry Ehman’s reaction to it, has never been heard again. But a few astronomers hope to find the mystery behind the source of the signal in the next few years and (hopefully) probe the possibility of a life beyond our planet.
