Scientists Report New Clues on Two Mysteries of Earth’s Inner Core

Scientists have reported new findings that could help explain two unresolved mysteries about the structure and behavior of Earth’s core, according to Infobae.

The Spanish-language news outlet published the report on Monday, September 7, 2026, but did not provide full details of the study or the researchers involved. The article states that investigators have identified clues that may shed light on these long-standing questions, though the specific nature of the clues or the puzzles themselves was not elaborated in the available summary.

Earth’s core, located roughly 2,900 miles beneath the surface, has been a focus of scientific inquiry for decades. Because direct observation is impossible, researchers rely on seismic waves from earthquakes to infer the core’s properties. Two persistent mysteries have involved the inner core’s unusual rotation and its unexpected structural variations, which have defied simple explanation.

Infobae’s report suggests that the new clues could advance understanding in these areas, but the summary does not specify whether the findings relate to rotation, composition, or thermal dynamics. Without access to the full article, it remains unclear what methods were used or what data supported the conclusions.

The report adds to a growing body of research that aims to refine models of the planet’s deep interior. Such work has implications for understanding Earth’s magnetic field, which is generated by movements in the outer core, and for interpreting how the planet’s internal heat drives geological processes.

What to watch next: Further details from the original study, including peer-reviewed publication, will be needed to assess the significance of these clues and whether they resolve either mystery.
