Google marks 44th anniversary of Arecibo message with a doodle

The Arecibo message sent in 1974 is a three-minute interstellar radio message carrying necessary information about humanity and Earth sent to aliens in the hope that they would receive and decode it. November 16, 2018, completes 44 years of that hope to communicate with the clusters of stars residing about 25,000 light years away from Earth. Even were this message received, M13 is so far away we would have to wait nearly 50,000 years to hear an answer.

These digits were multiple of two Prime numbers that could be arranged in a grid with 73 rows and 23 columns. If arranged in a particular way, the note is created to explain basic information about humanity and Earth to extraterrestrial beings.

It is known as "Arecibo Message" because scientists created and sent the message from the Arecibo Observatory in Puerto Rico.

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.

Astronomer and astrophysicist Frank Drake from Cornell University wrote the message with the help from American astronomer Carl Sagan, among others. But there was another goal for this experiment - to display the capabilities of the upgraded Arecibo telescope.

"Since 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), humankind will have to wait a long time for an answer".

The Arecibo Message was aimed towards the globular star cluster Messier 13, 25,000 light years away, in an attempt to contact extraterrestrial intelligence.

So far, the message has travelled 259 trillion miles, leaving 146,965,638,531,210,240 or so miles to go, although scientists never expected it to reach its final destination.

"It was strictly a symbolic event, to show that we could do it", Donald Campbell, a professor of astronomy at Cornell University, said in a statement in 1999.
