Astronomers beam music to space hoping for reply in 25 years
Astronomers from the US-based alien-hunting organisation METI have beamed electronic music samples to a potentially habitable planet about 12.4 light-years away in hopes of receiving a reply in 25 years. Music is a natural universal language and the transmission also contains a tutorial so that possible aliens could interpret the binary encoded Earthly tunes, said METI President Douglas Vakoch.
