Solar flare

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.

An X-class flare, the most powerful type of solar flare, erupted from the sun on Feb. 9, 2024. Lucky for us, Earth wasn't in the direct firing line.

In the final hours of Dec. 31, 2023, the sun launched its most powerful solar flare in 6 years. On Jan. 2, radiation from the blast may bring auroras to Earth's skies.

A recent solar explosion that almost reached "X-class" status has hurled a massive coronal mass ejection toward Earth, which will likely hit our planet and trigger a geomagnetic storm on Dec. 1.

Scientists have spotted an aurora signal caused by electrons accelerating through a sunspot on our star's surface for the first time ever.

Around Halloween in 2003, a series of massive solar storms erupted from the sun, including an absolute monster coronal mass ejection (CME) that remains the most powerful solar outburst in modern records.

High radiocarbon levels in the rings of subfossil tree stumps suggest that an incomprehensibly powerful solar storm, known as a "Miyake event," smashed into our planet more than 14 millennia ago.

The sun has launched a surprise CME directly at Mars, which could spark auroras and damage the Red Planet's atmosphere when it hits on Sept. 1.

Scientists studying a star system in Orion witnessed one of the most powerful stellar eruptions ever seen — and it could be devastating to nearby planets.
