Colliding plasma ejections from the Sun generate huge geomagnetic storms — studying them will help scientists monitor future space weather.

How space weather works Today, experts believe that the 1859 geomagnetic storm, now known as the Carrington Event, was caused by at least one, or possibly two, coronal mass ejections (CME).

GPS positions were off by up to 230 feet during the Gannon Solar Storm in May 2024 in a disruption that lasted for up to two days, a new study has revealed.

Solar storms pose no direct risk to humans, as long as they’re shielded by the Earth’s atmosphere. So if you’re not in space, you’re fine. In fact, they make for great viewing of the ...

If Earth happens to be in the path of the enhanced solar wind generated by one of these events and gets hit, you get a geomagnetic storm. On Feb. 4, 2022, SpaceX launched 49 satellites as part of ...

A solar storm is projected to impact Earth this Saturday, potentially bringing with it a dazzling celestial light show – and a few crucial questions about our increasingly connected world. While ...

14,300 years ago, a solar storm struck Earth that was so powerful, were to hit us today, it could result in worldwide blackouts that would last for years.

But the upcoming solar storm is expected to be strong enough to “overpower” that. A different story might be cloudy skies. “If it’s cloudy, you’re not going to see it,” he said.

The last big solar event to have a notable impact on a power grid was in 2003, Fiori said, when a number of geomagnetic storms known as "the Halloween storms" rerouted aircraft, affected GPS systems ...
