The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13. It was meant as a demonstration of human technological achievement, rather than a real attempt to enter into a conversation with extraterrestrials.
The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico on 16 November 1974. The message was aimed at the current location of M13 about 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. The message forms the image shown here when translated into graphics, characters, and spaces.
The message is a series of 1,679 bits that were arranged into 73 lines of 23 characters per line. Let us tell you that these are both prime numbers, and may help the aliens decode the message. It was sent to a cluster of stars 25,000 light-years away from the earth.
There are seven parts in the message from top to down which can show the numbers one to 10, atomic numbers of elements including hydrogen and oxygen, the formulas for the sugars and bases in the nucleotides of DNA, a graphic of the DNA double helix structure, a figure of a human and the population of the earth at the time, a graph of the solar system and a graph of the telescope.
