The northern lights are best seen between 10 p.m. and 2 a.m. local time while at a high vantage point away from light ...

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 ...

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

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, ...

Solar material is gusting out of the dark patch in the Sun's corona towards Earth at more than a million miles per hour.

According to the monitoring data, following the flare, the level of impact of solar X-ray bursts on the Earth's ionosphere increased to the R1 (weak) level, on a five-point scale topping out at R5, or ...

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

Intense solar flares—sudden bursts of electromagnetic radiation from the Sun—can shoot out hazardous levels of energy strong enough to reach Earth’s atmosphere. Predicting solar flares, ...
