#2. The Wow! Signal Mysteries
The search for alien life is something that has eluded mankind for decades. In the 1970s we have come very close to solving the mystery once and for all, following a series of unexplained radio signals picked up from space. Radio telescopes in the mid-70s picked up a sudden high frequency radio signal from outer space beaming towards Earth. Researchers later penciled the mystery signals with a large red “Wow!” which eventually gave the data its name. Whilst attempts were made to make contact again with the signal, the frequency has never been detected again, leading many people to assume that it came from alien life.
