There’s a moon mystery that’s been visible from Earth for500 years?and astronomers still haven’t figured it out.
Mark Pilkington writes in The Guardian that in 1540, beforethe first telescope was invented, stargazers in the Germancity of Worms saw a star-like object appear on the moon. In1650, the Polish astronomer Hevelius noted the appearance ofa “red hill” in the north-western moon area, and in April1787, astronomer Sir William Herschel saw so many red lightsin this same crater that he thought he there must be avolcano on the moon. NASA has also recorded hundreds oflight flashes, glows, mists, unusual shapes and shadows, allin the same area. They are known as Transient LunarPhenomena (TLP)?but nobody knows what they are.
