A collaborative project dubbed “ A Sign in Space ” is a achiever of the2024 Gizmodo Science Fairfor simulate a message to Earth from intelligent alien . The project involved beaming an encoded message from a Mars planet and inviting the public to decipher it , offering a unique glimpse into how humanity might respond to the challenge of read a content from an entirely unknown refinement .
The question
Could we trace an alien message if it reached Earth , and could we conjointly make horse sense of something entirely unfamiliar to us ?
The results
On May 24 , 2023 , aMars planet transmitted a radio signal to Earth . The ExoMars Trace Gas Orbiter , a mission that launch in 2016 to learn the Martian atmosphere , beamed out an strange subject matter that was pick up by three observatory on Earth 16 second afterwards . Although the transmission did n’t in reality descend from aliens , it highlighted just how intriguing communication between two distant worlds would be , suggesting that find an foreign signaling might not be the hardest part of name first physical contact .
The SETI Institute , a non - profit that ’s on the lookout for electromagnetic signatures of advanced exotic civilisation , organized the event ( SETI itself stands for the Search for Extraterrestrial Intelligence ) . The European Space Agency ’s mission control essence sent the secret message to the spacecraft , where it was stash away in its memory . The ExoMars satellite then convert the message into telemetry ( or digital data ) and beamed it as radio waves back to Earth .
The signaling itself was an encoded message developed by artist Daniela de Paulis , the founder of the interplanetary art projection , A Sign in Space .

“ While I was developing this task , I was thinking how former human must have been find when , for example , they were face up with natural phenomena that they could not explain , ” de Paulis said . “ They must have been create an account of these events together … so I ’m very fascinated by this process , how smart set works to seek to give meaning to realness . ”
uranologist at the Green Bank Observatory in West Virginia , the Allen Telescope Array in California , and the Medicina Radio Astronomical Station in Italy who receive the signaling , removed the telemetry and posted the message on the projection ’s website for anyone to download . 1000 of masses have attempted to decipher the alien code , switch idea online over what it could mean .
The content itself is only a few kilobyte in sizing , and it had to be extract from the balance of the raw data received during the contagion , but the content of the message remains unknown , except by de Paulis and two others . “ The message opus was the most difficult part . I was really losing sleep over it , ” de Paulis said . “ Everything seemed not suitable for a substance to be send by another civilization . ”

Wael Farah , a radio stargazer who help capture the sign at the Allen Telescope Array , was unsuccessful in render to decipher the encoded message , but he has some theory . “ What I call back it is , it ’s some reflexion of who we are as man , ” said Farah . “ At least that ’s what I think it would be , or I hope it would be , something that reverberate or projection about who we are as humans . ”
The experiment foreground just how challenging it can be to make horse sense of an unknown signal . It also highlights the collaborative effort take , much like what we might face during a real first contact with an alien civilisation . The team want to show that making contact with aliens would not play out the same way it does in the movies ; it would require month of testing to ensure the unity of the substance . The first affair scientists would have to do is to verify the transmission is n’t coming from a human spacecraft and that it can be received in the exact same form by different telescopes , which is why the psychometric test involved three lookout .
Why they did it
A Sign in Space blends art and science to prepare humans for the theory that an alien civilization might extend to out to Earth , while also allowing us to reflect on our own earth based on how the message is represent .
“ As an artist , what I was concerned in was to explore this process of imply making , so my question was : What if we take this really ultra form of theatre and we present humanity with a scenario where we simulate the response of an extraterrestrial message ? ” de Paulis said . “ We will have to make meaning of something that is completely outside the overall nature of our own culture , and I was really fascinated by this possible action … how can we make meaning of something while having no parameters ? ”
The project also exuviate light on the ongoing hunting for life beyond our planet . “ We ’re thread this care because there have been program in the past five to 10 class that have transformed this estimation that SETI is not just a crowd of people with tin hat on , ” Farah allege . “ It ’s a genuine scientific , astrophysical plain on its own and it deserves academic respect . ”
Why they’re a winner
Around 400,000 hoi polloi downloaded the signal a week after it was stop on Earth . “ We could see an pastime right at the first , ” said Franck Marchis , a senior planetary stargazer at the SETI Institute who coordinated outreach for A Sign in Space .
Marchis was offer the probability to know the contentedness of the message , but he refused for fear of foil it . “ In my mind , the signaling is the alien telling us that they know we ’re here , ” Marchis said . “ They just want to assure us that they know we ’re here and this is what they get it on about us . ” The discourse trigger by the project , even within the team itself , was the exact purpose of A Sign in Space .
“ We got a sight of different ideas … some of the approximation are right smart more interesting than anything we considered or what we uploaded , ” de Paulis said . “ We gave the message this fluidness , which earmark for several stages , to emphasize the idea that noesis is always a procedure — it ’s never all crystalise . ”
What’s next
The team behind the undertaking is still monitoring the online treatment surrounding the ‘ exotic ’ signal . De Paulis hopes the world ’s attention wo n’t focus solely on the subject matter of the substance but will remain open to various interpretations .
In terms of finding a straight signal from extraterrestrial life , the SETI Institute team is still scanning the creation . “ I will wager that we will find lifetime in our solar organization in the next 10 to 15 old age , ” Marchis said . “ In terms of exoplanets , that ’s going to be the next genesis of instruments that will probably take an image of an exoplanet like Earth with an ocean and maybe signatures of biological life , and this will happen when we launch new telescopes . We will then get an figure of another pallid blue dot . ”
