Sunspot AR3767 erupted with a X1.7-class solar flare, followed by an X1.1-class flare from sunspot AR3780. NASA's Solar ...

A erupted with M1 and M6 class solar flares. Watch the fireworks in these views from NASA's Solar Dynamics Observatory.

The powerful belch of material ejected during a solar flare may be way hotter than scientists thought it was. A new mathematical analysis suggests that the engine driving solar flares is far more ...

Forecasters expect a coronal mass ejection and a powerful X-class solar flare could impact the Earth starting on Thursday.

Research by university scientists suggests that solar flares may be far hotter than previously believed, offering new insights into the Sun’s behavior. The findings, recently published in the ...

What processes are responsible for heating solar flares and what dangers do they pose to Earth? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an ...

The sun has erupted with a series of powerful solar flares over the past 24 hours, including an X8.3-class flare — the most intense solar event recorded in 2026 so far. This extraordinary burst of ...

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

The solar corona is threaded by magnetic fields that are difficult to measure directly, yet they govern coronal heating, jets ...

The northern lights could mean lights out for the infrastructure we rely on.
