Using data from the Miniature Radio Frequency (Mini-RF) instrument onboard NASA's Lunar Reconnaissance Orbiter (LRO), a team of researchers came to the conclusion that the lunar subsurface contains a higher concentration of certain metals, such as iron and titanium, than estimated.

The study, published in the journal Earth and Planetary Science Letters, contends the most popular theory surrounding the Moon's origins. The hypothesis contends the satellite was formed when a Mars-sized object collided with Earth, vaporizing large portions of the Earth's upper crust.

"By improving our understanding of how much metal the moon's subsurface actually has, scientists can constrain the ambiguities about how it has formed, how it is evolving and how it is contributing to maintaining habitability on Earth," lead study author Essam Heggy said in a statement.
