Google in doodle remembers a transfer made to search for intelligent space in space



Google have remembered through a doodle The most powerful transfer to space 44 years ago in Puerto Rico: the famous Arecibo Message.

A group of scientists at that time tried the first communication of humanity with intelligent lives beyond our own planet. "It was a three-minute radio announcement, a series of exactly 1 679 binary numbers (one multiple of two prime numbers) that could be arranged in a grid of 73 rows of 23 columns, pointing to a group of stars of 25,000 years of earth's light" he explained Google.

The transfer was made with the intention of displaying the radio telescope's capacity of 1,000 feet (304,8 meters) in diameter.

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

Cornell researchers worked with the message with the famous astronomer Carl Sagan. The content can be organized in a rectangular grid with 0 and 1 to form a pictogram of basic content: mathematics, human DNA, the planet's place in the solar system and an image of a human being.

The curious thing is that Arecibo Message has not yet reached its estimated destination, nor is it close to doing it. It will take about 25,000 years to reach a group of 300,000 stars in the constellation of Hercules called M13. Since its transmission, 44 years ago, it has traveled only 259 billion miles, only a small part of 146 965 638 531 210 km to its final destination.
