Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

The last complete reversal of the Earth's magnetic field took place 42,000 years ago. Radiocarbon analyses of the remains of kauri trees from New Zealand now make it possible for the first time to ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Using this method, [efeyenice983] found that the Earth’s magnetic field strength at their location was about 0.49 Gauss, which is well within 0.25 to 0.65 Gauss that is typically found on the ...

Other factors contributing to the magnetic field–and causing it to vary wildly in intensity from place to place on the globe–are the Earth's crust, the ionosphere (50-375 miles up), the ...

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from. A 3.7-billion-year-old record of our planet ...

Earth's magnetic field became weaker during this period, falling to at least 5% of its present strength. This made it possible for more cosmic rays to enter the Earth’s atmosphere, according to ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.

Earth’s trusty magnetic field has been keeping the planet safe for at least 3.7 billion years. There’s a chance it might have formed even earlier than this, but the evidence is shaky and less ...

Earth's magnetic field may not be heading toward a dramatic flip anytime soon, according to scientists who analyzed anomalies in the planet's invisible shield against solar wind and other radiation.
