A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense ...

The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most ...

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.

In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio ...

The flare was part of a series of three X-class solar eruptions that occurred between late February 1 and early February 2.

Multiple M-class and X-class solar flares erupted within 24 hours as an active sunspot released intense radiation affecting ...

Recently, the sun has experienced intense activity, producing 18 M-class flares and three X-class flares, including the powerful X8.3 flare, the strongest of 2026. This surge originates from sunspot ...

The X8.1 flare was accompanied by a coronal mass ejection (CME), a significant release of plasma and magnetic field from the sun's corona. Modeling suggests that the bulk of the material from this CME ...

Solar Orbiter captured the most detailed view of a solar flare, observing the build-up of events that lead to the explosion.

F or all of its life-sustaining energy, the sun is pretty chaotic. Roiling plasma covers its surface along with fluidic snarls of magnetic fields that birth solar flares. These fiery outbursts occur ...

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter ...

Solar Orbiter observations show that a medium-class solar flare formed through cascading magnetic reconnection events, ...
