Sónar Festival is celebrating its 25th anniversary by attempting to contact alien life with music from Autechre, Laurel Halo, Nina Kraviz, Holly Herndon and more.

The ambitious project titled “Sónar Calling GJ273b” is described as the first radio message ever sent to Luyten’s Star with the help of the EISCAT (European Incoherent SCATter Scientific Association) antenna in Norway. The goal is to reach a nearby habitable planet and a return message has the potential to return in 25 years — just in time for the festival’s 50th anniversary.
