As part of their 25 year anniversary, We Are Europe partner Sónar festival from Barcelona created a special project called Sónar Calling GJ273b. From the EISCAT facilities just outside of Tromsø, musical messages were sent into space after their visit in October 2017. The objective is to reach the possibly hospitable planets circling the exoplanet Luyten Star b, a red dwarf 120 Trillion km away from earth, hoping to make the first human contact with an extra-terrestrial intelligence. Crazy eh?
