Large parts of the United States faced a radio blackout on Thursday following a strong solar flare from the sun. The "extreme ultraviolet flash" was captured by NASA's Solar Dynamics Observatory ...

Watch footage of the Sun unleashing an X1.2-class solar flare. NASA's Solar Dynamics Observatory captured the fireworks in ...

Solar flares can affect us on Earth, and radiation from this flare caused a shortwave radio blackout. A map released by the ...

Sunspot region 4114 has unleashed its most powerful solar flare yet — an X1.9 class that erupted late June 19, triggering ...

Solar flares are huge eruptions of radiation, and they’re classified in a letter system. C-class storms are the weakest, M-class storms are moderate and X-class flares are the strongest.

Three more moderate solar flares followed, and we could see more eruptions in the coming days. The sun has already produced more X flares in 2023 than 2022, as it's ramping up to peak activity.

Sunspot region 4114 has fired off its strongest blast yet — an X1.2-class solar flare that erupted on June 17, triggering ...

This X8.7-class flare was the strongest seen so far in this solar cycle, and stronger than anything from the Sun in more than 6 years.

Solar flares are closely related to another solar phenomenon called a coronal mass ejection, or CME. Where there's a flare, there's likely to be a CME, just like where there's smoke there's fire.

Solar flares decrease as the sun nears solar minimum. So, throughout the 11-year solar cycle, flares may occur several times a day or only a few times per month, according to NASA.

Solar flares are the largest explosive events in our solar system. They directly affect the ionosphere—where Earth’s atmosphere meets space—and affect radio communications.

Strong solar flares can send huge clouds of plasma into space. This is known as a coronal mass ejection (CMEs), and when they hit the Earth they can cause geomagnetic storms and intense aurora.
