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 ...

Scientists have discovered that the 'weak spot' in Earth's magnetic field is growing, allowing harmful radiation to come closer to our planet's surface. The region, known as the South Atlantic ...

The authors combined their results with previous measurements to establish that the Earth's magnetic field was at this weak level for at least 26 million years, from 591 to 565 million years ago.

The authors propose that the weakening of the magnetic field may have led to the increase in oxygen, which is believed to have supported the evolution of some of the earliest complex organisms.

Today will be the shortest day of your life. Our lives, too. Everybody's lives. According to those who keep up with atomic ...

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 ...

The generally weak emissions from the polar region have been much stronger, which makes it easier to obtain coronal magnetic field results in the polar regions. [Related: Rare quadruple solar ...

Their starting assumption was that the early Moon had a dynamo that generated a weak magnetic field 50 times weaker than Earth's. The results confirmed that a large asteroid impact, ...
