In his latest book, A World Full of Demons, astronomer and popularizer of science Carl Sagan said that even if aliens are short, harsh and sexually obsessed creatures, he wants to know about them. Humanity has been trying for a long time to find signs of the existence of life outside the Earth and uses a variety of ways to do this. For example, in 1977, NASA sent two Voyager spacecraft with gold-plated disks outside the Solar System, in which the most important scientific discoveries, DNA molecules, music and other information are recorded. It is expected that this disk will be found by alien civilizations and will be able to contact us. Recently, scientists decided to send an updated message to space for aliens — it is called a "Beacon in the Galaxy" and contains genetic data of people with a return address for communication. Some scientists fear terrible consequences in advance.
