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

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

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

The oldest firm age yet for Earth's magnetic field suggests that it developed before a solid planetary core, 3.7 billion years ago. When you purchase through links on our site, we may earn an ...

There Could Be a Hidden Link Between Earth's Magnetic Field and Oxygen, Say Researchers. The elements of the natural world had inherent connections, but new research brought to light one that was ...

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 ...

In 2013, the ESA launched three Swarm satellites for a mission to help decode how Earth’s magnetic field is generated by precisely measuring the radiofrequency signals coming from the planet’s ...

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.

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 ...

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 ...

Fluctuations in the strength of Earth's magnetic field—caused by daily changes in solar wind structure and intermittent solar storms—can impact the use of geomagnetic field models which are ...

Since the magnetic field is sustained by geological activity deep within our planet, let’s start with an overview of its structure. Although we’ve hardly scratched Earth’s surface (the center lies ...
