Geologic records reveal that magnetic field strength and oxygen levels rise and fall together, implying deep-Earth processes ...

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

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

NASA scientists revealed the mechanism 540 million years old, associated with a shift in the Earth's magnetic field, which ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Australia’s iconic bogong moths are the first creatures other than humans and some birds known to navigate by the night sky.

The strength of Earth’s magnetic field and the amount of oxygen in its atmosphere seem to be correlated—and scientists want ...

The moon may be silent and still today, but billions of years ago, it likely crackled with magnetic activity. Though the moon now lacks a global magnetic field, its rocks—especially those on the ...

Not only does this research offer new clues about how Earth has maintained the delicate balance needed for life, but it may ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...
