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

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 ...

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 ...

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

It may fall to 10 percent of the present-day strength and have magnetic poles at the equator or even the simultaneous ... magnetoreception that enables them to sense the Earth's magnetic field.

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 ...

During the past 180 years, Earth's magnetic field strength has decreased by about 10 percent. Simultaneously, an area with an unusually weak magnetic field has grown in the South Atlantic off the ...

Today, even with the Earth’s magnetic field at full strength, solar weather can pose a threat to sensitive systems. Solar flares and coronal mass ejections can fry communication equipment and ...

Earth's magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency ...
