The Wow Signal

A radio telescope detected an unusual signal on August 15, leading to the famous "Wow" moment when a volunteer physicist circled the unexpected characters on the printout. This narrow band signal, recorded near the 1.4 GHz frequency, raised questions about its origin and nature, as it appeared to be unlike any natural phenomenon known. Despite the excitement, the system's setup meant that any potential information in the signal was likely lost in the analysis process.
