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

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

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

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

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 ...

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 ...

The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its core fuses hydrogen atoms into helium, fueling the cosmic fire that ...

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 ...

This activity is part of the Science Friday Sun Camp collection! The Sun generates an incredible amount of energy, energy that you can see and feel as light and heat. Other forms of energy from the ...

The event could affect power grids and GPS. Earth is in the midst of a moderate solar storm – but will it be strong enough to cause technology disruptions? The National Oceanic and Atmospheric ...
