Some mysteries end. Not with a confession or a dramatic discovery, but with a patient explanation that fits the evidence better than the legend did. This is the shelf for the cases science has settled — or nearly settled — after years of work.

A case that is only partly explained stays in the main archive, with its status marked. If new evidence ever reopens a case on this shelf, it returns to the main archive.

For centuries, witnesses described glowing spheres drifting through thunderstorms, and science had no measurement to work with. In 2012, instruments on a high plateau in China caught one on camera and split its light into a spectrum — and found the signature of the soil it came from.
