Chinese researchers have presented a new map of the moon, updating a previous edition based on new scientific findings and recalibrating the moon's ancient geologic eras.
The comprehensive map of the moon, with a scale of 1:5 million, was unveiled by the Institute of Geology, Chinese Academy of Geological Sciences (IGCAGS) on Aug. 6. The map is an update of a 2024 edition and puts forward new boundaries for the ancient Aitkenian, Nectarian and Imbrian lunar periods.
