Answer 1

Answer:

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.[1]

This is a demonstration of the message with color added to highlight its separate parts. The binary transmission sent carried no color information.

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.[1][2] 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.[3] The message forms the image shown here when translated into graphics, characters, and spaces.[4]
