Arecibo Report: How researchers sent the first interstellar radio message and why they did



November 16, 2018 takes 44 years since scientists sent the first interstellar radio message to mankind – Google's success is celebrating Google Doodle.

The Arecibo message, which was sent from the Arecibo Observatory in Puerto Rico in 1974, is a three-minute message of precisely 1 679 binary digits – which, if arranged in a certain way, can explain basic information about humanity and the country to extraterrestrial beings.

Scientists have sent messages via frequency-modulated radio waves to star clusters of 25,000 light-years to demonstrate the power of the Arecibo radio telescope, which was at that time the largest and the strongest in the world.

"It was a strictly symbolic event that showed we could do it," said Professor of Astronomy at Cornell University, Donald Campbell.

The action has shifted to the presence of tears as researchers have considered their existence and knowledge of planets and solar systems.

The hope is that in many thousands of years it can reach other living beings.

The real message was developed by a team of Cornell University researchers led by astronomer and astrophysics Dr. Frank Drake.

Upon receipt, the message can be arranged in a grid of 73 rows of 23 columns to create a pictogram that represents facts about mathematics, human DNA, the planet Earth and man.

From a top-to-bottom seven-part report, numbers 1-10, atomic numbers of elements, including hydrogen and oxygen, formulations for sugars and bases in DNA nucleotides, double-helix DNA structure chart, human and land population numbers at that time, solar system chart and chart telescope.

Since sending the report, Arecibo has released only 259 trillion miles – a fraction of its journey to the intended goal of about 25,000 years.
