The Arecibo Report: Google celebrates the broadcast message in Space Technology and Science News



44 years ago, a group of scientists released a three-minute radio message with exactly 1 679 binary digits (a multiple of two prime numbers) per group of stars 25,000 light-years from Earth. This message is known as The message from Arecibo and Google Zebra today with a pudgy.

The report was launched from the Arecibo Observatory in the middle of tropical forests in Puerto Rico. Its goal is to test the first human communication with intelligent life outside the planet. For this purpose, the binary digits can be arranged in a grid of 73 lines of 23 columns.

The historical transmission also had the intention of demonstrating the capabilities of the recently-updated Arecibo radio telescope, whose 1000-foot plate made it the largest and the strongest in the world at the time.

"It was a strictly symbolic event to prove we could," said Donald Campbell, professor of astronomy at Cornell University, who was at the time a researcher at the Arecibo Observatory.

The report itself was created by a team of researchers at Cornell University, led by Dr. Frank Drake, a means to estimate the number of planets that carry extraterrestrial life inside the Milky Way Galaxy.

Drake had the idea of ​​doing something "magnificent". He wrote a letter with the help of Carl Sagan. We organized a system that could actually be arranged in a rectangular grid of 0 and 1 to create a pictogram representing some basic facts of mathematics, human DNA, Earth's planet space in the solar system, and human image – as a picture as well as the image of the telescope itself.

The The message from Arecibo It will take about 25,000 years to reach the target: a group of 300,000 stars in the constellation Hercules, known as the M13. If humanity accepts a response to a message, it will take a long time to come. For now, the report has traveled from the original 146,965,638,531,210,240 miles to only 259 billion kilometers.
