'Strange signals' detected from a star 11 light-years away
Puerto Rico-based astronomers claim to have detected "strange signals" supposedly coming from a red dwarf star 11 light-years away and 2,800 times dimmer than the Sun. The team believes the signal might also arise from a man-made satellite passing overhead, or energy bursts from nearby astronomical objects. The alien hypothesis is highly unlikely, researchers said, but wasn't ruled out.
