Scientists have confirmed that the moon has a fluid outer core and a solid inner core, similar to Earth's. The inner core is made up of a metal with a density similar to iron and measures about 500 kilometers in diameter. The findings were based on seismic data from moonquakes and modeling with different core types. The study aligns with a previous NASA study, lending credibility to the conclusion. However, mysteries about the moon's magnetic field and other aspects of its structure remain unsolved.
Scientists have discovered that the Moon has a solid core, similar to Earth, and have provided an explanation for the presence of iron-rich materials on its surface. By combining various techniques, researchers have revealed the internal structure of the Moon, confirming the existence of a solid inner core and a fluid outer core. They also propose the hypothesis of a lunar mantle overturn, which explains the movement of material within the Moon's mantle and the presence of iron-rich elements at the surface. These findings contribute to our understanding of the solar system's history and phenomena such as the disappearance of the lunar magnetic field.
Scientists have discovered a massive structure beneath the Moon's South Pole-Aitken basin, weighing at least 2.18 billion kilograms and measuring over 300km in depth and 2,000km in length. The anomaly could be composed of metal from an asteroid or oxides from a magma ocean. The finding was made using NASA's GRAIL mission, which measures changes in the Moon's gravitational field, providing insights into its internal composition and history.
