Photos in the gold disc of spacecraft sending aliens

Voyager two probes carried two gold recordings containing images and messages from Earth launched in space since 1977.

In 1977, the US Aerospace Agency (NASA) launched Voyager 1 and Voyager 2 probe into space with the desire to learn more about Jupiter and Saturn. The two satellites have completed their mission, although the communication equipment is quite primitive compared to modern standards. Moreover, Voyager 2 goes further to gather information from Uranus and Neptune. Wang. Currently two probes have flown out of the solar system, into interstellar regions, and Voyager 1 is the most artificial object far from Earth. Knowing that the two probes will continue to travel in the universe after the mission is over, scientists decided to put each ship a message from the Earth in case they were found by outsiders. planet.

In 1976, under the agreement of the council of American astronomer Carl Sagan and 13 other scientists, two gold records were placed on each ship. There are 116 photos depicting life on Earth, a message expressed by 55 languages, other sounds such as wind, waves, thunder, animals and 90 long music. Minutes from different cultures and countries. Two recordable discs mounted on the outside of the ship, on the engraved shell, explain how the disc is run using universal symbols and constants in the hope that extraterrestrial civilizations can understand.

Images depicting human activity: licking, eating, drinking.There is also a photo of building a house in Africa, going on the Great Wall, catching fish, grilling fish, Chinese family meals, eating grapes, and some other photos of life.(Photo: NASA).

Council members also provide instructions with simple drawings based on math and science that they believe aliens can decipher. Some photos are highly pragmatic, instructing the person to have a record of how to decode numbers, and measuring distances. Other images show different aspects of human life, how people eat, drink, cook, smoke, dance, play music and play sports.

DanceTo simulate human art, scientists also put violin photos, music tracks, orchestras into gold discs.(Photo: NASA).

Some give details about anatomy, reproductive process, so that aliens have a clearer view of human biology.There are 8 human anatomy images recorded in gold plates.(Photo: NASA).

City of Oxford.There are photos of major cities such as Oxford, Boston, Sydney, Taj Mahal, photos of the United Nations building taken during the day and night, Pakistani streets and Indian streets.(Photo: NASA).

Scientists have also tried to include music in the disc with as many artistic nuances as possible. In addition to Beethoven's Symphony No. 2 and Chuck Berry's Johnny B Goode, there are also Peruvian panpipes, tribal music in Zaire (Republic of Congo), and traditional Georgian choral music. Sagan personally decided to record "Dark Was the Night, Cold Was the Ground" on the disk, according to him, the song "describes the loneliness in the universe".

The probe also carried the message of the then-President of the United States Jimmy Carter, in which he wrote to the civilization that found the ship: "This is a gift from the distant little world, a sign of yin. Our bar, science, pictures, music, thoughts and feelings ". "We will try to survive in our time to be able to live with you." Maybe because the Cold War is going on when the record is designed, its message of peace continues to inspire people to this day.

Some images of the Earth and the Earth's surface are sent: photos of drifting continents, woodlands, dunes, rivers and forests.(Photo: NASA).

Voyager 1 is 19.9 billion kilometers from Earth, its electrical equipment is expected to exist until 2025 when the internal generator stops working. The ship is drifting in the wrong direction but will fly over a star of the Big Bear, Gliese 445, 1.6 light years away from the star within 40,000 years.
