A moderate geomagnetic storm can cause minor issues for satellites, GPS signals and high-frequency radio communication. Some power grid systems in higher-latitude countries may also see small ...

The sun has just fired off an eruption so intense it ranks among the most powerful solar flares seen in three decades, a jolt of energy that has put space weather forecasters and power grid operators ...

A solar storm is a catchall term that describes any disturbance in the sun that involves the violent ejection of solar material into space. This can come in the form of coronal mass ejections, where ...

A G1 geomagnetic storm is forecast for February 15 as a CME and high-speed solar wind reach Earth, increasing chances of Northern Lights at higher latitudes.

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

India's Aditya-L1 mission has uncovered why Earth's magnetic field behaved strangely during recent solar storms. A new study explains how polar electric currents reached the equator.

India's Aditya-L1 mission has revealed why Earth's magnetic field reacted unusually during two massive solar events in 2024.

Scientists have long relied on tree rings to learn about ancient solar storms—rare bursts of high-energy particles from the sun that can disrupt satellites, power grids, and communication systems ...

Increased solar wind and coronal mass ejections can lead to more intense and dynamic auroras.
