This transmission aimed to demonstrate the capabilities of the recently upgraded Arecibo radio telescope.
The Google doodle is celebrating today the 44th Anniversary of the Arecibo message, an interstellar message sent to a group of stars in space with anticipation. Extraterrestrial intelligence could receive it and decipher it.
Forty-four years ago today, a group of scientists gathered at the Arecibo Observatory amidst the tropical forests of Puerto Rico for the first attempt at communicating with intelligent life beyond our planet, said Google
The three-minute radio message – a series of exactly 1,679 binary digits (a multiple of two prime numbers) that can be arranged in a grid of 73 rows on 23 columns – aimed at a group of stars, M-13, 25,000 light-years from Earth
The show was powerful because it used Arecibo's megawatt transmitter connected to its 305-meter antenna. The latter concentrates the energy of the transmitter by radiating it in a very small part of the sky.
This historical transmission was intended to demonstrate the capabilities of the recently upgraded Arecibo radio telescope, whose 1,000-foot parabola made it the largest and most powerful Google
"Given that the message of Arecibo will take about 25,000 years to reach its destination (a group of 300,000 stars in the constellation Hercules known as the M13), humanity will have to wait a long time For 44 years as the message has been transmitted, the message has traveled only 259 trillion kilometers, a tiny fraction of the 146 965 638 531 210 240 of its final destination, "said Google.
Dr. Frank Drake, then at Cornell University and creator of Drake's equation, wrote this message with the help of Carl Sagan, among others.
