Attempts to Contact Aliens

It might be that the messages people send to aliens are just shots in the darkness. In the early 19th century, the Austrian astronomer Joseph Johann von Littrow made a serious suggestion: people should dig many ditches to form giant geometric patterns in the Sahara Desert, then fill them with kerosene, and set them on fire. The purpose of such an idea was to send a clear message to alien civilizations living somewhere in the solar system: we are here. It was neither the first nor the last one attempt to contact the other civilizations. What results can be expected?

Radio Waves and Russian Scientists

The idea of Joseph Johann von Littrow was never implemented as it was not very realistic. However, even many years after this ambitious plan, people did not stop trying to look for a contact. Radio communication has become the first more realistic way to communicate. In 1962, Soviet scientists directed a radio transmitter to Venus and greeted the planet using the Morse code. This first introduction of its kind consisted of three words: mir (a Russian word meaning peace or the world), Lenin, and the USSR. The message was considered symbolic. It was most akin to a test of a whole new space radar. It is a technology that sends radio waves into space. Its main purpose is to observe and display the objects of the solar system.

Second Serious Attempt

In terms of distance, the next attempt to reach extraterrestrial civilizations was far more ambitious. In 1974, a team of scientists, including astronomers Frank Drake and Carl Sagan, transmitted the Messier 13 radio message from the Aresibo Observatory in Puerto Rico to a star cluster that was 25,000 light-years away. The image message sent in binary code included a graphic human figure, a DNA double helix graphic structure, a carbon atom model, and a telescope diagram.

The message of Aresib in the literal sense of these words was shots in the dark. It would take about 25,000 light-years to reach Messier 13. But by the time the message reaches it, the swarm of stars will have already moved, says Cornell University’s Department of Astronomy. Hypothetical aliens still can detect a penetrating signal because its intensity is 10 million times stronger than the radio signals sent by our Sun. The sun emits a wide range of electromagnetic radiation, from electromagnetic to radio waves. However, this is still an unlikely coincidence.

Spaceships and New Ideas

Attempts to connect with aliens were not limited to radio waves. Spaceships with Earth artifacts also were set, hoping that they would eventually be caught in space by aliens. In 1977, the Voyager 1 and Voyager 2 spaceships were launched. The aim was to explore the farthest corners of our solar system and interstellar space. Both spacecraft have a golden disk, a message from humanity, made up of things like music, ambient sounds from Earth, and 116 images of our planet and solar system. Voyager probes are still flying in interstellar space and waiting for someone to discover them. But what is the probability that this will happen? “Zero,” says Sheri Wells-Jensen, a scientist at the University of Bowling Green who specializes in extraterrestrial civilizations.
