Google dedicates the dude to mark the 44th anniversary of the Arecibo message



November 16, 2018 marks 44 years since researchers sent the first interstellar radio message of humanity – the achievement of Google celebrates with dude.

Dudley is characterized by colorful alien beings, designed by Gerben Steenks.

Forty-four years ago, a group of scientists gathered in the Arecibo Observatory in mid-tropical forests in Puerto Rico to try the first communication of humanity with intelligent life beyond our planet.

A triple radio message, a series of exactly 1,679 binary digits (multiple of two free numbers) that could be deployed in the network of 73 rows from 23 columns – was targeted to a cluster of stars of 25,000 light-years away from the earth.

The scientists sent a message through frequency-modulated radio waves to a cluster of stars of 25,000 light-years to show the power of the Arecibo radio telescope, which at that time was the largest and most powerful in the world.

This historic transfer aimed to demonstrate the capabilities of the recently upgraded radio telescope Arecib, whose container of 1000 ft has become the largest and the strongest in the world at that time.

"It's a strictly symbolic event to show that we can do it," said Donald Campbell, professor of astronomy at the University of Cornell, who at the time was a research associate at the Arecibo Observatory. However, some of the attendees were moved to tears.

The message itself was designed by a team of researchers from Cornell University headed by Dr. Frank Drake-Astronomer and an astrophysicist responsible for Drake's equation, tools for estimating the number of planets living extraterrestrial life in the Milky Way galaxy. "What could they do spectacularly?" Drake said. "We could send a message!"

Written with the help of Carl Sagan, the message itself could be arranged in a rectangular network of 0s and 1s to create a pictogram representing some basic facts in mathematics, human DNA, the planet Earth in the solar system, and the image of a man as well as the image of the telescope itself .

After the message was sent to Arecibo, the message passed only 259 trillion miles – part of its journey to the desired destination, which would last about 25,000 years.
