Humanity has always wondered if there is someone in the Universe besides us? Where do aliens live? Do they know that we live here on Earth?
We will tell in this article about people who tried to open the veil of secrecy about alien beings.
One day, two astronomers, Margaret Turnbull and Jill Tarter, who worked at the Carnegie Institution in Washington, DC, compiled a list of 17,129 nearby stars that, according to various estimates, may have planets capable of forming and supporting intelligent life. Criteria were put forward according to which the potential of the planets was estimated: the stars must be at least 3 billion years old, since time is a necessary condition for the development of life. They must have a low mass and a high iron content in their bodies, because metals are needed to form rocky, Earth-like planets. The "leader" on this list is Epsilon Indi A. It is a dull orange star located just 11.8 light-years from us, in one of the corners of our galaxy, the Milky Way.
Scientists have identified the most suitable places for alien life in our solar system. These include the underground spaces of Mars, hydrothermal points on Saturn's lunar moon Enceladus (at whose south pole geysers are common) and Jupiter's moons Europa and Callisto (under whose ice crusts vast underground oceans of water are hidden).
And what is known about attempts to contact aliens and tell about our existence? There is information that in 1960 at the National Radio Astronomy Observatory of West Virginia, astronomer Frank Drake made the first scientific attempt to establish communication with alien beings. He used an 85-foot radio dish to listen to signals from two nearby solar stars. You haven’t heard about it, because the search for it turned out to be nothing but a zilch.
And in 1972, scientists even made an attempt to tell aliens about humans. Carl Sagan and Frank Drake designed a special plaque showing a naked man and woman and placed it in the Pioneer 10 spacecraft. The next step was to send soundtracks about life on earth. Two Voyager probes, launched in 1977, carried a 12-inch gold-plated record with the sounds of whales, greetings in 55 languages and a Bulgarian folk song on board. Just in case, NASA also included a phonograph stylus and game instructions. And on September 30, 2006, the French Center for National Space Research broadcast the space program "Space Connection", intended for aliens, on a solar star named Errai, 45 light years from Earth. The video for them should reach them in 2051.
