The new study provides unambiguous evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface. USC scientists have proven that the Earth's inner core ...

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth. We use this information to estimate the core's ...

USC scientists have made a groundbreaking discovery about the nature of Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing. The ...

Alfred Wilson-Spencer receives funding from NERC grants NE/T000228/1 and NE/V010867/1. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of iron and ...
