In a dramatic escalation of solar activity, the sun has unleashed an X8.3 flare — 2026’s strongest yet — causing radio blackouts as scientists monitor Earth-directed CMEs ...

The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades. Far from the steadily glowing orb we ...

The most intense type of solar flares emitted by the Sun is the X-class, and several of them in a short period of time is ...

The Sun unleashed a powerful X8.3 solar flare on Feb 1, 2026, triggering R3 radio blackouts. Explore the impacts of the year's strongest eruption.

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 ...

A few days ago, Europe and Africa were hit by unexpected radio disturbances, surprising communication operators. The origin ...

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

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 ...

Solar flares are sudden releases of energy from the Sun’s surface. Scientists categorise them based on strength, beginning with A, B and C, followed by M and finally X.

This Feb. 4, 2026, image from NASA's Solar Dynamics Observatory (SDO) captures a strong solar flare erupting from the star.

The Sun released a strong solar flare on Tuesday, Feb. 3, following several eruptions in the preceding days, prompting increased geomagnetic storm activity. Nasa’s Solar Dynamic Observatory captured ...
