It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At most, Earth's magnetic field may have remained at 25 percent of its current ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

Every few hundred thousand years, Earth’s magnetic poles flip, turning north into south and south into north. These ...

The Pacific seafloor laid down around 10 million years ago is dramatically enriched in beryllium-10, compared to older and ...

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

A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing ...

Earth's inner core has changed shape over the past 20 years. A team of scientists studied the core's behavior to understand why its rotation slowed down ...

“Regarding the impact on life, as mentioned in the paper’s introduction, inner core growth plays a crucial role in generating Earth’s magnetic field, which protects us from harmful solar ...

Combining experiments in microfluidic devices and computer simulation, this study provides a valuable analysis of the relevant parameters that determine the motility of (multicellular) magnetotactic ...

A powerful solar storm in May 2024 led to the formation of two radiation belts, altering Earth's space environment.
