METI (Messaging Extraterrestrial Intelligence) scientists have sent out music, math and technology to a potentially habitable planet named GJ273.
The message makes a direct link the type of radio signal and the content included, providing clues for any alien life to decipher.
They beamed the transmission in three blocs during the Sónar music festival in Barcelona, making the total transmission last 13 minutes.
With their next step being sending an extended message, the scientists will be waiting for a reply until June 21st, 2043.
Worries Of alien invasion
The decision to beam messages has always been controversial. The SETI (Search for Extraterrestrial Intelligence) institute say that we should be actively searching for alien life by listening out for signals.
Stephen hawking has often defended this position and strongly arguing against the METI organisation.
In his eyes, Alien life that is capable of visiting us, we would see ourselves in the same situation the Native Americans were when Columbus landed in America.
However, Douglas Vakoch, president of METI, said in an interview with Newsweek that we shouldn’t be worried about an alien invasion: “Any civilisation that could travel to Earth to do us harm could already pick up our leakage television and radio signals. So there’s no increased risk of alerting them of our existence”.
