Google Doodle Celebrates 44th Anniversary of First Interstellar Radio Message - Arecibo Message

The broadcast holds significance because it demonstrated the power of the Arecibo radio telescope, which was the largest and most powerful in the world at the time. The Aricebo message is a three minute communication comprising of 1,679 binary digits. This "historic transmission" was meant to be a demonstration of the capabilities of the recently upgraded radio telescope at the Observatory.

"It was strictly a symbolic event, to show that we could do it", said Donald Campbell, a professor of astronomy at Cornell University who was a research associate at the Arecibo Observatory at the time of the message.

Dr. Frank Drake, then at Cornell University and creator of the Drake equation, wrote the message with help from Carl Sagan, among others.

The Arecibo message-interstellar radio message- was sent into space, encoded with several information about humanity so that extraterrestrial intelligence could receive and decipher it. The message can be arranged in "a rectangular grid of 0s and 1s to form a pictograph" of fundamental mathematics facts, human DNA, the location of Earth in our solar system, "a picture of a human-like figure" and a photo of the telescope.

#The atomic numbers of the elements hydrogen, carbon, nitrogen, oxygen, and phosphorus, which make up deoxyribonucleic acid (DNA). The messages are sent in hope to come in contact with extraterrestrial intelligent beings so we could learn and explore more about us and our universe.

"Several searches for extraterrestrial intelligence are now underway, including one where you can use your own home computer". It was sent during the dedication of an upgrade to the Arecibo radio telescope November 16, 1974, and translated into a warbling audio tone that was broadcast over speakers.

The mankind will have to wait a long time for an answer, as the Arecibo Message will take roughly 25,000 years to reach its intended destination (a group of 300,000 stars in the constellation Hercules known as M13). To do the math, the message has only reached 259,000,000,000,000 (259 trillion) miles which is a tiny fraction of the total journey that will be about 146,965,638,531,210,240 miles long.
