In 1977, scientist Jerry R. Ehman discovered the ‘Wow! signal’ which was detected by the Big Ear radio telescope during a SETI project. The intensity of the signal has been interpreted as a special message sent from an extra-terrestrial source. 35 years later, National Geographic replies to this message with tweets as part of its Chasing UFO TV series.
Hundreds of tweets, and short video clips were sent through, ranging from greetings, and comical messages, to the more serious. On 15 August, NatGeo celebrated the 35th anniversary of the original Wow! signal by transmitting the messages using the world’s largest ground-based radio telescope in Puerto Rico.
