Google Doodle marks 44 yrs of 1st interstellar radio message
Google on Friday celebrated the 44th anniversary of mankind's first interstellar radio message with a Doodle. The three-minute-long message was sent by Puerto Rico-based Arecibo Observatory with an aim of transferring information to alien life. It contained human DNA, Earth's position in the solar system, mathematical facts, a picture of a human-like figure and an image of the telescope itself.
