One way to track the solar cycle is by counting the number of sunspots, which are dark, cooler patches on the Sun’s surface.

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field.

How can astronomers observe and study the Sun’s activity in the most efficient way despite the Sun and Earth orbiting each ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are ...

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity. Over the past couple of years, solar activity—as measured by ...

Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes ...

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The ...

A team of researchers who had previously issued an alternative solar forecast that turned out to be better than NASA's claims the sun's activity will peak next year. When you purchase through links on ...
