Alien tripod by Alvim Corréa, 1906 French edition of H.G. Wells’ “War of the Worlds”

A researcher suggests that the “techno signature” of the trash might be a discarded reflective surface, rotating:

If only a few hundred mirrors were present, a much smaller telescope could spot one. But the fact that we haven’t seen such flashes yet suggests any alien visitors—if they are out there—are doing a good job of cleaning up after themselves.

Paper. (open access)

We invent explanations for not seeing the trash, quite apart from the fact that we have never seen the aliens. There, you stupid peasant, that’s real science thinking for you.
