Solar Storm of 1859

Learn how violent solar storms shower Earth with radioactive atoms.

Auroras may once again be visible in northern parts of the U.S. this weekend as Earth braces for impact from a powerful coronal mass ejection.

A rare geomagnetic storm lit up skies, eerie AI demonstrations and a cautionary word about raw milk.

David Wallace of Mississippi State University talks to Deborah Byrd about solar flares and the impact a big storm from the sun would have on Earth today. The post Will solar flares destroy modern civilization? Nah first appeared on EarthSky.

Years of careful planning helped safeguard against last weekend's severe space weather, but we still don't know how we'd cope with a monster event

A beastly sunspot that's 15 times the diameter of Earth remains highly active — and you might be able to spot it with your eclipse glasses!

Did you save your eclipse glasses from the April 8 total solar eclipse? If so, grab them to check out giant sunspot region AR3664, now facing Earth! The post Giant sunspot region now visible in eclipse glasses first appeared on EarthSky.

A sunspot so big it rivals the gigantic sunspot responsible for the Carrington Event in 1859 has unleashed another X-class solar flare. Watch the eruption...

Sunspot AR3590, which recently spit out three X-class solar flares in under 24 hours, has grown even larger and is now pointed almost directly at Earth, putting us in the crosshairs of more potential eruptions.

A geomagnetic storm, active January 22 to 23, means sky watchers could be in for a spectacular show.

The latest discovery of a Miyake-level solar storm only emphasizes that the disasters have struck with some regularity throughout history and likely will again.

An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps.

When a major solar storm hit in 1859, "telegraph systems worldwide went haywire." Here's what to know if such an event were to hit today – and how likely it is to happen.

The Sun's activity has increased in recent months, and the peak of its life cycle, previously expected in mid-2025, seems to have moved to this year

As questions abound about the Earth's closest star, scientists are seeking answers critical to forecasting solar flares that threaten satellites and other electronics.

When two coronal mass ejections collide in interplanetary space, they can create an even more powerful storm. Recent research explores exactly which characteristics can turn solar storms from moderate to severe.

The dark patches resembling eyes and a grin are actually known as coronal holes, which...

Expect another mostly sunny day ahead with a high in the low 90s.

Extreme solar storms can cause widespread disruption to our everyday lives, just like pandemics.
