sónar calling

Celebrating its twenty-fifth anniversary, the music, creativity and technology festival Sónar that just concluded in Barcelona, as BLDGBlog informs, is sending transmissions, short samples of electronic music to a potentially inhabited exoplanet via a high-gain radio station in Tromsø, Norway. The second of two signal bursts, it’s projected to arrive at Luyten β (GJ 273b)—orbiting a stable red dwarf star and among the most Earth-like planets discovered to date—by 2030 with a reply another dozen years in the waiting.
