Deep beneath our feet lies a realm that continues to intrigue and mystify scientists: the Earth’s core. Recently, new ...

Scientists have uncovered surprising evidence that helium, a gas long thought to be chemically inert, may actually bond with ...

In June 2024, USC scientists published a study showing that Earth’s inner core has been slowing since 2010. This deceleration slightly affects the planet’s rotation, leading to marginally longer days.

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

Some of that helium-3 became trapped in Earth’s core when Earth formed. We recently saw a lot of excitement around the discovery of helium-3 in moon crystals because of how rare this isotope is ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than previously thought ...

Although more than 99.95% of Earth's gold is locked in the molten core, tiny amounts may be coming up to the surface in magma, a study found. A lava fountain at Kilauea in Hawaii is seen in early May.

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

Ancient oceans with phosphorus-rich waters may have supported some of Earth’s earliest microbial life, according to a new ...

Microbes have been discovered alive inside 2-billion-year-old rock, offering a rare window into Earth’s deep past. Found in ...
