Message into the universe

Is there any life in space beyond Earth?

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.

However, researchers are not only listening attentively into space: astronauts are exploring further and further into the unknown. They invent new technologies and solution to overcome obstacles, that can make our lives on Earth more sustainable as well. And that is what the campaign “From Space to Life” by the initiative Research in Germany is all about! Learn more at: From Space to Life - Research in Germany (

  • 1974: The Arecibo-Messages

    In the early 1970s, researchers at the famous Arecibo Observatory in Puerto Rico had a brilliant idea: They wanted to prove that we are not alone by sending a message into space - a message that could potentially be received by extraterrestrial civilisations.

Here we needed 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.

What would you tell unknown life forms about humanity? What message would you like to send into space? Together with Research in Germany, we were interested in your ideas for messages into space.
