To celebrate its 25th anniversary, Sónar launches a message beyond the Earth's orbit in search of extraterrestrial intelligence in an exoplanet called GJ273b, potentially habitable and 12.5 light-years from us.

This message consists of the music of 33 artists, whereas scientific researchers specialised in searching extraterrestrial intelligence, coding and sending data to space have collaborated to make it possible.

In this session, full details of Sónar Calling will be presented by scientists that shaped this project: astrophysicist Ignasi Ribas, who studied the feasibility of the project, and telecommunications engineer Jordi Portell, author of the tutorial to decode music for the inhabitants of this exoplanet. Both researchers are part of the Institute of Space Studies of Catalonia (IEEC), specialised in space research and its applications. Canadian astrophysicist Yvan Dutil, responsible of sending music to space, will also participate.

Two of the artists that created the music that forms this intergalactic message will join this talk: Barcelona-based Austrian producer Zora Jones and Icelandic artist Ólafur Arnalds.

This session will be moderated by Lluís Nacenta.
