Interstellar messaging
Bebo is collaborating with the RDF Media Group to send 500 messages to the planet Gliese 581c which is more than 20 light-years away but the nearest good candidate for a neighbouring extraterrestial civilisation. Some have criticised this action because it might draw unwanted attention to Earth, provoking an attack or other inimical action.[18]
