“We were meeting on a monthly basis, brainstorming ideas on what a possible extraterrestrial civilization would send to us.
“I was working with astronomers, anthropologists and other scientists, it was a very interdisciplinary group, and we also had artists from different fields,” she said. “It will take some time, because it requires people with different expertises to collaborate with each other, which was really the objective of the project: an extraterrestrial message would belong to all humanity, so we should all have the ability to contribute to its interpretation.”ĭe Paulis, who is also a licensed radio operator, started working on the project, called “A Sign in Space,” in 2021. “I can’t really say anything about the content of the message, and we’ll only start giving some hints if we see that people really struggle,” said SETI member Daniela de Paulis, the artist who created the message, in a phone interview. A few days on, the collaborative effort is still ongoing, and a Discord channel has been set up for public discussion. Once received, the raw data containing the message was released on the internet via Filecoin, a large decentralized storage network, to give everyone a chance to decode it and interpret its meaning.
The ExoMars Trace Gas Orbiter, shown here, played a key role in SETI's test by sending a message to Earth on May 24. The transmission traveled across space for 16 minutes before being successfully picked up by three observatories: the Allen Telescope Array in Northern California, the Green Bank Telescope in West Virginia, and the Medicina Radio Astronomical Station near Bologna, Italy. The message went out on May 24 from the ExoMars Trace Gas Orbiter, a spacecraft launched in 2016 that is currently orbiting Mars to study its atmosphere. It is meant to explore the process of decoding and interpreting an intelligent signal from the cosmos and how it would impact humanity. The event - organized by SETI, a nonprofit organization with a mission to search for extraterrestrial intelligence and explore the origin of life in the universe - straddles the line between art project and technical rehearsal.
What would happen if aliens contacted us? It’s a longstanding question that now has at least a partial answer, after a transmission designed to mimic correspondence from an extraterrestrial civilization made its way to Earth from Mars.
