Signals bounced off reflectors on the lunar surface return surprisingly faint echoes on full moon nights. Scientists think it's the result of uneven heating of the reflective lenses, which would alter their refractive index, dispersing the return beam, and they found compelling evidence for this explanation during an eclipse as Earth's shadow passed over each reflector in turn.
