"Astronomers have discovered unusual signals..." There are lots of 'unusual' radio waves in the universe; astronomers discover them almost daily. May of them are variable. But there's that word 'signal' again. Crap science journalism likes to play on the connotations, the suggestion of purpose, of meaning. Dictionary says: "An indicator, such as a gesture or colored light, that serves as a means of communication." "the astronomers tried to find the object in visual light. They found nothing." Fairly usual for radio objects. That's why they were missed until Reber came along. An interesting anomaly, I get that. Rouses the curiosity. Just stop with the 'signal' please, until it fits the case.
