The Arecibo message was a binary-encoded message sent to M13 globular cluster in 1974 from the iconic Arecibo Observatory in Puerto Rico. It was designed as an interstellar radio message intended to be a means of communication with potential extraterrestrial civilizations. The message consists of a pictorial representation, which includes 1,679 binary digits, arranged in a grid of 73 rows and 23 columns. The content of the message contains information about our solar system, the Earth's position, the structure of DNA, the human figure, and other fundamental scientific and mathematical concepts..
