Life on Earth would be impossible without the moon – it maintains the stability of the axis of rotation of our planet and supports the change of seasons. However, still being about how the Moon formed. A popular hypothesis States that the Moon was formed from the body the size of Mars that collided with Earth. However a new study gives a new understanding that can challenge the previous versions.
The analysis, published in the journal Earth and Planetary Science Letters, sheds new light on the composition of dust found on the bottom of the craters of the moon. The ESS Heggie (Essam Heggy) from the School of engineering of the University of southern California and his team examined the data from the Lunar Reconnaissance Orbiter on the composition of fine dust in the craters. The researchers came to the conclusion that the moon may be richer in oxides of metals than believed scientists.
The team found higher concentrations of metals in the deeper craters. Scientists say that may be a higher concentration of the metal deeper underneath the surface. Conclusions questioning the current understanding of how the Moon formed, since the satellite is richer in metals than the Earth. Alternatively, a greater amount of metal may hint at the sophisticated cooling of early molten surface of the moon.
