Astronomers and astrophysicists have expressed doubts over the wisdom of choking the airwaves around Earth with radio signals.
Top astronomers have warned that "space spam" messages could annoy or even threaten extraterrestrials and that we should be more careful about what we send out in to space and how they might be interpreted.
European Space Agency (ESA) astrophysicist Malcolm Fridlund advised caution about drawing attention to ourselves. "I'm not lying awake at night worrying about the overlords of the galaxy or anything like that," he told AFP, "but when you don't know of anything that's out there, you should maybe be a little careful, you should know something about the (star) system first."
