A team led by geoscientists Yachong An and Hao Ding of Wuhan University have determined that Earth's inner core wobbles with a periodicity of 8.5 years.
The location of the north magnetic pole has moved by about 965 kilometers since the first measurement was taken in 1831. This could indicate the beginning of a field reversal, but scientists really can’t tell with less than 200 years of data.
Water from Earth's surface can find its way deep into the planet, and new research explains how it changes the outermost region of the metallic liquid core.
Long ago, an alien planet crashed into Earth – causing a collision so big the debris formed the Moon and left mysterious remnants lodged deep in the Earth’s mantle.
Record concentrations of a helium isotope found inside 62-million-year-old Arctic rocks could be the most compelling evidence to date of a slow leak in our planet's core.
An international study found that certain groupings of iron atoms in the Earth’s inner core are able to move about rapidly, changing their places in a split second while maintaining the underlying metallic structure of the iron.
The most high-resolution map yet reveals something we previously never knew about: an ancient ocean floor that may wrap around the core. This thin but dense layer exists around 2,900 kilometers below the surface.
U.S. recent study revealed a layer between the Earth's core and the mantle that is likely a dense, yet thin, sunk ocean floor.
The new layer of the inner core consists of an iron-nickel alloy, like other parts of the core, but it has a different crystal structure.
Chinese scientists say that based on their calculations, a small imbalance in the electromagnetic and gravitational forces could slow and even reverse the inner core’s rotation.
The length of our day changes slightly over a six-year period. This recent discovery has perplexed scientists for about a decade and now we know the reason for it - it is the Earth core.
The enhanced growth on one side of the core suggests that something in Earth’s outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil.
Recent study shows that beneath the Yellowstone volcano lies a so-called mantle plume: a chimney-like structure that reaches thousands of kilometres deep to the border of the Earth's core and mantle.
Satellite observations of the Earth's magnetic field reveal a fast-moving stream of metal deep inside the planet.
