It’s notoriously difficult to predict when the sun will belch out a large solar flare — an explosive burst of radiation that ...

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ...

NASA's Interface Region Imaging Spectrograph (IRIS) mission captured an X1.1-class solar flare. See time-lapse footage of the blast that caused "a strong shortwave radio blackout over South America," ...

Scientists have long struggled to accurately predict solar flares, but a recent breakthrough using NASA’s Solar Dynamics Observatory has uncovered a promising new sign: flickering coronal loops. These ...

Coronal mass ejections when aimed at Earth, they collide with our magnetic field within days, setting off geomagnetic storms that can disrupt satellites, interfere with GPS systems, and even threaten ...

What is space weather, what causes it, and how does it affect humans? Physicist Robyn Millan, who co-chaired a recent ...

Auroral activity is best seen between 10 p.m. and 2 a.m. local time while at a high vantage point away from light pollution, ...

There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at ...

As the sun geared up to spit a powerful solar flare into space, NASA scientists snapped huge loops of plasma leaping from the sun's surface. These spectacular solar structures, known as coronal ...
