Earth’s magnetic field is responsible for the brilliant northern and southern lights. But more importantly, it protects Earth’s surface and atmosphere from harmful radiation, making life possible.

Could humanity one day terraform Mars by smashing Mercury into it? In this fast-paced Q&A, Joe Scott tackles wild and thought ...

The region of space dominated by Earth's magnetic field is the magnetosphere. Observations have shown that, within this ...

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

Abstract: Jupiter's radio emission has been linked to its planetary-scale magnetic field, and spacecraft investigations have revealed that most planets, and some moons, have or had a global magnetic ...

Additionally, it is thought that the reason Mars is dry and arid today, despite having flowed with liquid water in its distant past, is because of the lack of a planetary magnetic field. This ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could ...

It could also help scientists learn more about planetary magnetic fields in general, like why Jupiter and Saturn have such different fields, she said. Juno will continue to orbit Jupiter until ...

If the poles were to reverse, Earth's magnetic field would dip to 20% strength, possibly for centuries. Such an event would plunge our current global communications system into disarray.

Gallagher noted that the sun's magnetic field reverses every 11 years. Mars had a global planetary magnetic field, too, but it doesn't any longer.

Astronomers have now, for the first time, detected magnetic fields in the central stars of four planetary nebulae, suggesting a cause of the irregular structures.

“Humanity has only ever had one planetary magnetic field to study as recorded in rocks – Earth’s,” Wiens said. “Being able to study Mars – which we think once had an Earth-like magnetic field and lost ...
