The journey of the human template message from Arecibo would take 22,800 light years to reach Messier 13. It took a tiny fraction of that to receive a reply however. Expecting the transmission to take 22,800 Light Years might have been an exaggeration when, in reality it may reach life much earlier. In fact, the transmission has now traveled nearly 43 light years from Earth (252 trillion + miles) - towards M13, and has passed the distance of the closest star from our Sun which is 4.3 light years away. It takes only approximately 1 minute to reach Mars traveling at light speed for perspective, or 1.23 seconds to reach the moon.
27 years later, in 2001, a crop circle appeared in the form of a response to the 1974 Arecibo broadcast appeared right next to Britain’s largest telescope, the Chilbolton, and observatory, home to the world’s largest fully steerable meteorological radar. It’s one of the most amazing crop circles to ever appear, regardless of whether you believe it was done by human beings or an extraterrestrial intelligence. The message describes a different solar system, an image of the sender (just like on the original NASA message), non-human DNA, and a microwave antenna instead of the radio-wave antenna that was depicted in ours. What’s also interesting to note is the fact that the microwave antenna signal in this crop circle also appeared a year earlier in the exact same field. Like most crop circles, it was written off as a hoax within the mainstream.
