Earth's Inner Core Composition. ... High-resolution seismic X-ray imaging, machine learning, and even next-generation neutrino detectors may help them map the inner core in greater detail.

Scientists believe that Earth’s core is a massive ball of iron.However, a new discovery suggests that the Earth’s core is surrounded by an unexpected ancient structure. A high-resolution map ...

Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal ...

A thin, yet dense, sunken ocean floor could be deep between the Earth’s core and mantle. The findings of a new study published April 5 in the journal Science Advances used global-scale seismic ...

Earth’s inner core is a roughly 1,500-mile-wide sphere made mostly of iron and nickel. It sits inside the planet’s liquid outer core, which itself is nestled beneath the mantle and crust. The inner ...

Today, Earth’s core is actually two pieces. There’s an outer layer of molten metal about 1,795 miles thick. Inside that layer of molten metal lies a solid sphere of iron and nickel: the inner ...

Earth’s solid iron inner core appears to be spinning at a slower rate than the planet, according to a new study — but no worries, scientists believe it’s been changing speeds and directions ...

Research on how the different parts of the Earth interact is important to help scientists understand Earth’s inner core composition and geomagnetic field, Brown said. The study quoted by CNN, ...

Scientists have discovered that our planet's core has been rotating at a slower rate for nearly 15 years -- and it could mean longer days for some. The wheel of time isn't turning like it used to.

A team of researchers have determined a new pressure scale, which is critical for understanding the Earth’s composition. Using x-rays from a uniquely powerful spectrometer at RIKEN’s SPring-8 ...
