The 500,000-mile wide hole has cracked open the sun's atmosphere, leaving a gap over 62 times the diameter of Earth from which high-speed solar winds are now shooting towards us

The effects of a coronal mass ejection—a bubble of plasma that bursts from the sun’s surface—will likely impact Earth’s magnetic field on Saturday, bringing the northern lights to several northern U.S.

A massive coronal hole has opened on the sun, sending high-speed solar wind toward Earth and increasing aurora activity.

Aurora chasers are on high alert for minor geomagnetic storm conditions from Jan. 24 through to Jan. 25. Northern lights might be visible over some northern and upper Midwest states.

Researchers have created an improved traffic light system for predicting geomagnetic storms. They are now testing how well these algorithms can prepare us for incoming space storms that can wreak havoc by knocking out satellites in space and power grids on Earth.

The National Weather Service has issued a winter weather advisory for the Sacramento area until Sunday at 4 p.m., with wind gusts up to 55 mph and a 70% chance of rain, and the Placerville area expecting 4 to six inches of snow.

A vast 500,000-mile-wide coronal hole has opened in the Sun's atmosphere. The area measures over 62 times the diameter of Earth and is now shooting high-speed solar wind toward Earth.

Solar storms pose a rising threat to power grids, satellites, and communications. Experts call for urgent preventive measures.

NASA warns of solar storms disrupting global tech, power grids, and satellites, urging upgrades, collaboration, and preparedness to protect a tech-dependent world.

Aurora chasers are on high alert as a minor geomagnetic storm is expected to hit Earth soon, potentially triggering spectacular northern lights displays in the northern hemisphere.

Another display of the northern lights could be visible this weekend in several U.S. states following a severe solar storm. The National Oceanic and Atmospheric Administration Space Weather Prediction Center forecast a planetary K-index -- which characterizes the magnitude of geomagnetic storms - of five out of a scale of nine for Friday and Saturday,

A minor or greater geomagnetic storm is expected following the arrival of a coronal mass ejection emitted from the sun on Jan. 2, NOAA said, which could result in some power grid fluctuations and ...
