The sun has released several powerful M- and X-class solar flares over the past few days, resulting in radio blackouts around ...

On 14 May 2025, the Sun erupted with the biggest flare we've seen all year. From the eastern limb of the Sun – that is, the left side – active sunspot region (AR) 4087 erupted in a huge, X2.7 solar ...

X2.7-class eruption from sunspot AR4087 disrupts radio signals as the active region rotates toward Earth, raising the risk of ...

so the sun's magnetic fields get twisted up over time. Eventually, the field lines snap back into alignment, which we call recombination. It's like snapping a rubber band, and it releases lots of ...

X-class flares are the strongest and most intense on the solar scale. Earlier this week, the National Oceanic and Atmospheric ...

Scientists hope that the craft will also be able to help answer some big questions, including how are solar winds formed and ...

These advances, which allow scientists to capture intricate details of solar flares and map the sun's magnetic fields with increasing precision, are crucial for understanding its complex processes ...

This illustration lays a depiction of the sun's magnetic fields over an image captured by NASA’s Solar Dynamics Observatory. The complex overlay of lines can teach scientists about the ways the ...

In magnetic reconnection, adjacent magnetic field lines break and snap together to form new lines. This process converts magnetic energy to both thermal energy, or heat, and kinetic energy ...
