Radioactive spike found in Pacific seabed samples. It could be from space radiation or changes in ocean currents 10 million ...

Over 40,000 years ago, Earth's magnetic field pulled a switcheroo, flipping its poles in a dramatic shift known as the ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the ...

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

The largest solar storm in two decades hit Earth in May 2024. For several days, wave after wave of high-energy charged ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few ...

Scientists have captured magnetic signatures from Earth's ocean tides in the finest detail yet. These faint signals, which certain satellites can detect when flying at very low orbits, may hold ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...
