The sun released a powerful solar flare followed by a fast-moving coronal mass ejection on January 18, resulting in a ...

A massive X1.9 solar flare and coronal mass ejection lit up the northern skies with dazzling auroras captured by NASA.

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 ...

Sunspot AR3256 erupted with an X1.2-class solar flare. NASA's Solar Dynamics Observatory captured the fireworks in multiple ...

A powerful flare unleashed a severe solar storm that caused auroras and GPS disruptions on Earth.

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

Solar flares are powerful bursts of radiation. A SWPC report added that the storm calmed and reached G4 status again on ...

Earth's magnetic field was struck by a "severe" solar storm Monday (Jan. 19), triggering vibrant auroras in the U.S. and ...

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

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and ...

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.
