The Arecibo Message: Earth’s letter to extraterrestrials that hasn’t been picked up… yet

No one knows if there’s intelligent life out there. There are theories, hypotheses, simulations, and equations that tell us that there must be something more. Yet, for all their efforts, scientists haven’t identified any sign of intelligent life on another planet, only snippets of microbes possibly living in the acidic clouds of Earth’s toxic neighbour, Venus.

This isn’t through a lack of trying, however. On November 16, 1974, scientists working at the Arecibo Observatory in Puerto Rico broadcast a coded message containing information about mathematics, humanity, the Solar System, DNA, and the Observatory itself.

The end destination was Messier 13, The Great Hercules Cluster, a star cluster located some 25,000 light-years away from Earth.

The Arecibo Message was a groundbreaking moment in human and scientific history. Not only was it humanity’s first-ever attempt at Messaging Extraterrestrial Intelligence (METI) but the only one ever made.
