Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting ...

Here’s how it works. Earth's magnetic field — also known as the geomagnetic field — is generated in our planet's interior and extends out into space, creating a region known as the ...

But we do have some ideas about where the energy that heats the Sun’s atmosphere might be coming from, and it has a lot to do with the Sun’s magnetic field. Let me explain what this means.

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 ...

This entire process, from the moment the magnetic field was amplified to the time that it decays back to baseline, would have been incredibly fast -- somewhere around 40 minutes, Narrett says.
