A study concluded that the moon has a solid core similar to Earth

NASA suggested in 2011 that the moon has a solid, iron-rich core, as well as a liquid outer core.

scDoctors may have just opened post from the moon secrets. they It found evidence indicating that the moon’s inner core is solid, like Earth.

Researchers from the University of Côte d’Azur and the Institute of Celestial Mechanics and Ephemeris Calculations in France have developed models of the moon’s interior, hoping to shed light on our natural nature. The internal geological structure of the satellite. tHey designer that – that, Not only is the moon’s inner core as solid as Earth, however It is also made of a metal with a density close to that of iron. they It was also found that the core is about 310 miles (500 km) in diameter—about 15% of the total width of the moon. Arthur Briode and collaborators published their work this week in the journal nature.

The new analysis also yielded Evidence for a lunar mantle inversion, or Movement of material in the lunar mantle before this layer is cooled into essentially a solid mass. Scientists argue that this inversion of the mantle could explain why iron is present on the surface of the moon. As warmer material rose through the mantle, volcanic activity occurred on the Moon iron deposition on the surface, where it eventually cooled and split into soil.

While we know a lot about the moon’s structure and history, the new study It helps confirm and build on this pre-existing knowledge. NASA suggested 2011 The moon has a solid core rich in iron. As well as a liquid outer core. althougSE researchers used seismic data captured during the Apollo missions to paint a picture of what the moon’s inner layers looked like. this work It is estimated that the inner core is about 300 miles (482 kilometers) in diameter, and is close to at recent days group estimates.

Based on pre-existing datasets, such as those collected by NASA, the research team was able to build models of the moon’s internal structure. By matching physical observations of the moon’s gravitational fields, such as those taken NASA’s GRAIL missionAnd Briaud and his collaborators have developed simulations of the moon’s interior geology that better match these specific data points—The best match involved the hard inner core being described by the team. The process for inferring lunar mantle inversion was similar. The team created a numerical model of the lunar mantle based on thermodynamic data They found that the scenarios for the reversal of the moon’s bowels made of iron-rich material matched best with the current state of the moon.

this work It’s not the only effort to be exploring lately Alien lunar geology. in March , Published by researchers in China Evidence of a reservoir of water on the lunar surface in wet form glass beads. scientists from Chang’e-5 lunar lander Mission, suggested that little one Glass beads found in lunar regolith They are from asteroid impacts and can store water derived from the solar wind.
