As per the old belief all the planets in our solar system look similar beneath the surface. However, scientists have revealed different facts related to the earlier belief. A per the scientists, “the mantle of the Earth is made mostly of a mineral called olivine additionally, the assumption is usually there that states all planets are like the Earth," said Jay Melosh, Distinguished Professor of Earth.
The recent study by scientists shows that “when we look at the spectral signature of rocks exposed deep below the moon's surface, we don't see olivine”.
The scientists added, 4 billion years ago, an asteroid collided with the moon and created the largest and deepest impact on the moon. This collision called the South Pole-Aitken basin. The collision exposed lunar mantle in the basin and splashed up material onto the far side of the moon.
For the study, the research team created a three-dimensional simulation of the asteroid's collision with the moon to make sure they were looking for the splashed material in the right place.
