Forty years ago, Americans sent Voyagers into space – two spacecraft intended for the study of distant planets of the solar system. Among other things, Voyager 1 and Voyager 2 was supplied with messages to aliens. Specialists NASA hoped, and perhaps still hope, that representatives some extraterrestrial civilization will take possession of these probes, after which able to extract and understand the information on them.
Why do we need plates on Voyagers?
A gold plate was attached to the casing of each device. aluminum case. The plates on the Voyagers contain information about Earth’s position in our Milky Way galaxy, greetings on many languages of the world, music of various composers, sounds of nature, images of our planet, hydrogen atom diagram, anatomical human schemes, an appeal to aliens by President Jimmy Carter and much more. In short, NASA employees tried tell the “green men” as much as possible about our “blue ball “and the Solar System, without failing to clarify what exactly America sent these messages to space.

Today, Voyagers are the most distant from us. objects created on Earth. One probe has already managed to enter interstellar space while the other lingered in The solar system and hopelessly lagged behind his twin brother. If alien intelligent creatures really intercept data devices and decrypt messages on them, then it will become available to them information about where our small water world is located.
As markers for finding the Earth are 14 pulsars – space sources of radio, gamma, x-ray and optical radiation. These rotating neutron stars having their magnetic fields are ideal space landmarks. Indeed, in space there are no such concepts as “north”, “south”, “west” and “East”. Pulsars “live” for many millions of years, with each of They have a unique type of signal, so find such star and calculate the planets located “nearby” from it are not It should be of great work for an extraterrestrial civilization.
Was it wise to show the aliens the way to Earth?
Back in 1977, world scientists, including Soviet ones, unanimously recognized that sending such messages into space – great idea. However, over time, the ethical side of this issue became a serious subject of controversy among the people of science. Today many researchers claim that it would be better if humanity continued listen to space, instead of trying to be heard. Since it is far from the fact that the aliens will be friendly.

When the Voyagers were launched, scientists had no idea are there any outside the solar system exoplanets, not to mention the presence of reason on them. Now now thanks to projects like the Kepler Space Observatory, we it is known that planets are found in our galaxy relatively often, while many of them have all the conditions for occurrence of life. This revelation made many experts think. over whether our civilization should attract attention potentially existing green men.

But be that as it may, for Voyager 1 and Voyager 2 all a foregone conclusion. They already plow outer space and carry no one knows where the map showing the coordinates of our Earth. And if somewhere there are intelligent aliens capable of intercepting our probes, they probably will not be difficult to read the information on plates. However, the devices move at a speed of “only” 10 kilometers per second, and to the nearest inhabited planet they can fly millions and millions of years. It is possible that humanity that moment is simply gone.
Of course, there are other points of view. So, quite popular theory says that there wasn’t any sense, since aliens have long been here. They constantly visit our planet, build their base in Antarctica, volcanoes, under water and other places inaccessible to humans. However to mass contact with people for one reason or another are not in a hurry to go. Maybe, they just chuckle at our attempts with the Voyagers …
