☆ The mystery of how the moon formed is still puzzling scientists. The secret could lie deep within our planet.

AdvertisementHere are four leading theories of how the moon was formed, and why the secret to uncovering the truth could lie deep within our planet. The moon wandered by the Earth and was captured into its orbitAccording to the capture theory, the moon was wandering through the universe like a giant asteroid. NASA/NOAAThe moon formed alongside the EarthThe accretion hypothesis ties the moon to the birth of the Earth. The problem is that while the moon and the Earth share isotopes, the way they put them together is very different. The moon also pulls as the earth, scientists have found.

☆ Chunks of an alien world could be hidden deep within our planet, say scientists

This alien planet, Theia, was thought to have completely disappeared in the collision. AdvertisementAdvertisementAs well as shedding new light on the inner workings of our planet, scientists hope they will one day have access to these slabs of alien rock to reveal, once and for all, how our moon formed. The assumption has long been that Theia melded into moon, the Earth's mantle, and its core, in effect disappearing completely. Previous theories have suggested this core-mantle boundary could be made up of bits of ancient ocean floors. The problem is that the core-mantle boundary is very far from the surface — about 1,800 miles.

☆ Relics of Huge Primordial Collision Reside in Earth's Deep Interior

By Will DunhamWASHINGTON (Reuters) - Seismologists have recognized since the 1970s that two mysterious continent-sized blobs reside in the deepest part of Earth's mantle, one under Africa and the other under the South Pacific region. Based on these simulations, they proposed that most of Theia was absorbed into Earth, forming the blobs, while residual debris formed the moon. If the study's conclusions are correct, these blobs would represent the first direct evidence of the hypothesized moon-forming collision. "It is incredible because we can uncover relics of another planet - Theia - if we dig deep enough in Earth's mantle," added planetary scientist and study co-author Hongping Deng of the Chinese Academy of Sciences' Shanghai Astronomical Observatory. Asimow said that if their conclusions are correct some volcanic rocks that reach Earth's surface may provide samples of a vanished planet.
