Today Google Doodle is dedicated to 44th Anniversary of Arecibo Message which is the first interstellar radio message sent by humans in 1974.
The Arecibo Message:
November 16, 1974, Researchers in Arecibo Observatory, Puerto Rico has sent a three-minute message with 1679 binary digits decoding the basic information of humanity and Our planet Earth to the Extraterrestrial beings predicted to be in a cluster of starts 25,000 light years away to demonstrate the power of the Arecibo radio telescope, the most powerful radio telescope at that time! The message has traveled 259 trillion miles or a tiny fraction of 146,965,638,531,210,240 or its final destination is intended to reach.
The message was devised by a team of researchers from Cornell University led by Dr. Frank Drake—the astronomer and astrophysicist responsible for the Drake Equation, a means of estimating the number of planets hosting extraterrestrial life within the Milky Way galaxy. Assisted him was Carl Sagan. The message decoding will show the Earth’s place in the Solar System, Human DNA, Human figure, Fundamental facts of Mathematics and a picture of the telescope. Hope to get back from them soon!
