The sunspot region designated AR 14098 rotated over the Sun’s eastern limb in late January carrying magnetic complexity ...

Scientists say this powerful surge in solar activity could set the stage for the northern lights to appear as early as Thursday, Feb. 5 ...

The Sun fired off six X-class flares in the first four days of February 2026, a burst of extreme activity spanning roughly 400,000 miles of the solar disk. That stretch covers nearly half the Sun’s ...

The X8.1 flare was accompanied by a coronal mass ejection (CME), a significant release of plasma and magnetic field from the sun's corona. Modeling suggests that the bulk of the material from this CME ...

The Sun released a strong solar flare on Tuesday, Feb. 3, following several eruptions in the preceding days, prompting increased geomagnetic storm activity.

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

Space scientists have announced that the Sun has fired four massive solar flares. The outbursts were captured by NASA’s Solar ...

For instance, the X8.3 flare peaked at 6:57 PM EST, unleashing a torrent of ultraviolet and X-ray radiation that impacted the Earth’s upper atmosphere. Such intense solar activity can create a cascade ...

A G1 or G2-class geomagnetic storm is possible on Wednesday, Feb. 4, as a coronal mass ejection from a powerful X8-class solar flare struck Earth's magnetic field.

A surge of solar activity could trigger auroras.

NASA has reported a X4.2 solar flare, so what does it mean? We break down what a solar flare is and how it connects to the aurora Australis.
