The sunspot region 4366 fired off dozens of powerful solar flares in 24 hours, including the single strongest flare since 2024. Auroras are possible later this week.

The most powerful solar flare of 2025 has launched a ball of energy toward Earth that could trigger widespread auroras across the United States tonight.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

Record-breaking images from the world's largest solar telescope, the Daniel K. Inouye Solar Telescope in Hawaii, reveal a solar flare in unprecedented detail.

An astrophotographer has captured an extremely rare and "difficult" photo of a solar flare exploding from the sun at the exact moment the International Space Station passed directly in front of our home star.

Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering massive solar flares to erupt. This is the first time a planet has been seen influencing its host star.
