China’s Yutu-2 rover has spotted two strange glass spheres on the far side of the moon.
Glistening like translucent pearls against the moon’s dry and dusty landscape, the lunar “spherules”‘ are the first of their kind to be found on the lunar surface and formed fairly recently, researchers say.
Glass has been spotted on the moon before; by both the Yutu-2 rover and NASA’s Apollo 16 mission. It forms when silicon-rich minerals, such as pyroxene and feldspar, are rapidly superheated.
