People have been wondering about alien lifeforms for many years. Driven by this curiosity, the first message was sent into space as early as 1974 with the "Arecibo message" – response still pending. Scientists in SETI research (Search for ExtraTerrestrial Intelligence) are working on finding answers to the question of extraterrestrial life. They have already made various attempts to reach potential life in the universe. But what does interstellar contact actually look like? How are messages sent into space? And how do researchers figure out in which zones of other star systems extraterrestrial life is even possible? Five prominent experiments provide information about previous attempts and research results.
Message into the universe
Is there any life in space beyond Earth?
Now we need your creativity!
The "Arecibo message" contained information about the most important chemical elements for life on Earth and about our DNA. The data disks of the Voyager space probes from 1977 contain greetings in 55 languages and music by Louis Armstrong or Wolfgang Amadeus Mozart.
