Now that i am into Hambach topic again, a rather interesting earth related story just crossed my timeline.

On the satellite view i linked is the "Forschungszentrum Jülich", a nuclear research facility, visible at the bottom left.
Last week a team of archaeologists digging near the Hambach Forest to unearth remains of a roman villa discovered a sealed metal box containing 30 year old spy radio equipment in perfect condition
Probably hidden there by a spy covering the research facility after the east-block collapsed.

Earth is not only beautiful but full of surprises.
