If an intelligent alien civilization has ever sent unmanned probes to Earth, could we recover them ?
It stands to reason that if we were to have ever been visited by curious extraterrestrials then they may have sent unmanned probes to observe us at one time or another, something that we ourselves would undoubtedly do if we came upon an earth-like planet teeming with life. Could there be alien probes amongst the space debris in orbit around us now, waiting for us to come across them ?
As powerful space telescopes seek out Earth-like planets, and SETI radio telescopes listen for transmissions from aliens, physical evidence for intelligent extraterrestrials might be right in our backyard.
