There was a message received by the SETI’s Big Ear Telescope back in 1977 that is finally going to receive an Earthly response on August 15th, 2012. The frequency of the signal sits at a 10 kHz bandwidth around 1420 MHz, which is the same frequency at which hydrogen resonates. SETI researchers have been looking for this frequency because they believe aliens would send a signal using hydrogen since it’s the most common element in the universe.
The origin of the signal comes from the Sagittarius constellation. There is doubt as to whether or not it is a sign of intelligent life because they’ve never seen the signal again since its discovery in 1977.
All tweets composed between 8 p.m. EDT Friday (June 29) and 3 a.m. EDT Saturday (June 30) tagged with the hashtag #ChasingUFOs will be rolled into a single message, according to the National Geographic Channel, which is timing the Twitter event to coincide with the premiere of the channel’s new series, “Chasing UFOs.”
Then on Aug. 15, exactly 35 years after the Wow! signal was detected, humanity’s crowdsourced message will be beamed into space in the direction from which the perplexing signal originated.
“We are working with Arecibo Observatory to develop the best way to encrypt the transmission,” said Kristin Montalbano, a spokeswoman for the National Geographic Channel. “Earlier transmissions have focused on simplicity, whereas this one will rely more on creating a complex but noticeable pattern, hopefully standing out from other random, natural noise.
