7. The Wow! Signal

The Wow! Signal is a mysterious radio signal that was detected in 1977 by astronomer Jerry R. Ehman while working on the Search for Extraterrestrial Intelligence (SETI) project at Ohio State University.

The signal, which lasted for 72 seconds, was named the Wow! Signal after Ehman circled the data on the computer printout and wrote "Wow!" next to it. The signal appeared to come from the direction of the constellation Sagittarius and had characteristics that suggested it could be of extraterrestrial origin.

Despite numerous attempts to detect the signal again, it has never been observed or identified since its discovery. Many theories have been proposed to explain the Wow! Signal, including natural phenomena such as comets and asteroids, or even human-made interference.

The Wow! Signal remains one of the greatest mysteries in the search for extraterrestrial life, and its origins continue to elude scientists and researchers.

8. The Zodiac letters

he Zodiac letters are a series of cryptic messages that were sent by an unidentified individual who called himself the "Zodiac Killer" in the late 1960s and early 1970s. The letters, which included ciphers, cryptograms, and other codes, were sent to various newspapers and law enforcement agencies in the San Francisco Bay Area.

The Zodiac Killer claimed responsibility for a series of murders in the area and taunted the police and the public with his letters, often including details about his crimes that only the killer would know. Despite an intensive investigation, the identity of the Zodiac Killer has never been determined, and the ciphers and codes in his letters have never been fully deciphered.
