But how did it end up being this pure in most parts of the Moon? The secondary event that explains it, notes the report, is what researchers are calling a crustal overturn. Old impure plagioclase was replaced by hot, pure plagioclase as the moon cooled rapidly. Asteroid hits, space dust, and other harsh space conditions could have also sheared away the surface impurities, notes the report.
Because of the lack of atmosphere, there is no air temperature on the moon. Rather, it is measured by surface temperature. Different areas of the moon will have extreme temperatures, varying from boiling hot to freezing cold depending on whether the area is being hit by sunlight or if it is not.
