Scientists: The Earth’s interior has a secret core

You probably learned in school that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But new research has shaken up that picture, writes the site byte.

The inner core likely has another core inside, according to a team of researchers from the Australian National University (ANU).

The existence of this “deeper core” may have resulted from a tragic event early in Earth’s history.

“We found results that may indicate that the iron structure has changed, which may be due to two separate cooling events in Earth’s history,” Joanne Stephenson, a doctoral student at ANU, and lead author of a paper on this discovery. solid ground.

Earth’s core is a different iron structure

It cannot be said what the cooling process looked like and what happened. But using an intelligent algorithm to search packets of search data and model the inner kernel.

The idea of ​​another species came a few decades ago, but now it is also seen that iron may have a different structure there. At about a radius of what we consider the inner core, the iron crystals point in an east-west direction, not in a north-south direction.

“It’s very exciting — and it could mean we have to rewrite the textbooks,” Stephenson says.
