The WOW! Signal
By Logan Wright
Jerry Ehman was wowed when, on August 15th 1977, he received a radio signal from space that bore expected hallmarks of potential non-terrestrial and non-solar system origin.

The signal occupied a small range of frequencies around 1400 MHz. International agreements have outlawed broadcasts in that range, and almost all natural radiation signals have a significantly larger range of frequencies. Consequently, the signal’s source is very difficult to pinpoint.
The logical possibilities are a gargantuan radioactive event of some sort or a powerful transmission by an alien civilization. Naturally, most enthusiasts lean towards the latter. Skeptics, on the other hand, point out that any similar signals have always proven to be caused by interference. After 30 years, the argument rages on. Wow.
