This is precisely what we would expect to receive as a message from an extra terrestrial source – a reply to a radio message broadcast by SETI in 1974 as a hello from humanity to the stars. Close to 31 years later in 2001, this crop pattern appeared in a field beside the Chilbolton Observatory in Hampshire, UK. This response time could indicate that the sender inhabits a star system around either 30 light years away if their method of communication operates instantaneously or 15 years light years away if it is limited to the speed of light.
The Arecibo message was a series of binary digits transmitted towards the globular star cluster M13, with the hopes of communicating with intelligent extra-terrestrial life. The message contained information about human biology, our solar system, and our technology, among other things.
The response contains various clues as to who or what they are: biologically they are silicon based instead of carbon based with an extra strand in their DNA, they are significantly shorter than us with larger heads and they inhabit 3 planets out of 8 planets either in their star system or in our own as the solar system depicts 9 planets including a ring for Saturn and the gas giants highlighted as such. They use the same mathematical system as us and have an overall population of around 30 billion.
Most curiously we also have at the bottom a depiction of the device used to broadcast the message which also appeared as it’s own Agrogram the previous year in 2000.
