A sophisticated “muographic” scan of a well-trod Ancient Greek necropolis, a network of tombs, revealed a puzzling new area that could be a cramped burial chamber. But the researchers can’t confirm as no passage or stairway leads to the strange area.

To prepare for the sophisticated muographic scan, the researchers from Italy and Japan reviewed a more conventional laser scan of the tombs prepared by an Italian cultural heritage program. This had ferreted out all the special inlets to the necropolis , but the lasers missed the sealed off area because they were unable to pierce stone walls.
. It relies on special particles called muons created when cosmic rays collide with particles called nucleons in the upper atmosphere.says, “a perpetual muon rain” that varies by only about 5 percent over time. While muons fall steadily, they fall few and far between, meaning scans can take weeks on end.In this case, the researchers climbed down to a low, centrally placed chamber known as “Chianca,” a place used for ham aging during the 1800s.
