Researchers have pondered the moon's makeup for a long time. According to new research in Nature, the moon's inner core is a solid ball with a density similar to irons. It further states that the moon has a solid core like Earth's and that the lunar crust is iron-rich.
The outcomes are the product of teamwork:
CNRS, Universite Cote d'Azur
Observatoire de la Cote d'Azur
Due to its small size, its substantial core had yet to be discovered. In the study, the researchers noted that data from laser-moon ranging and other satellite missions corroborated the latter's presence.
The scientists continued by saying they found evidence of material changes in the moon's mantle (the layer between its core and crust) over its history (evolution). The lunar mantle's reversal explains the presence of iron-rich rocks on the moon's surface.
Science Alert states that in 2011, a team led by NASA Marshall planetary scientist Renee Weber produced similar discoveries.
