The Sun just fired off its most powerful kind of flare. At 1:09 p.m. EST on January 18, 2026, the Solar Dynamics Observatory recorded a dramatic burst of light and energy emerging from the Sun’s surface. Classified as an X1.9 flare, this event is part of the most intense category of solar flares — with the potential to disrupt life here on Earth. Solar flares are sudden explosions of energy caused by the tangling, crossing, or reorganizing of magnetic field lines near sunspots. This particular f

😯👉On February 4, the Sun unleashed an intense X4.2 solar flare, captured by NASA’s Solar Dynamics Observatory. Solar flares in the X-class category are the most powerful type, releasing enormous bursts of energy and radiation into space. This flare reached its peak at 7:13 a.m. Eastern Time and was carefully observed by researchers who track solar activity. Even though the radiation from flares like this cannot pass through Earth’s atmosphere to harm people on the ground, these eruptions can s

#FirstpostNews: Sun Releases Strong Flare, Energy Equivalent to a Billion Bombs The Sun released a powerful solar flare on February 3, following several flares in previous days. NASA confirmed it was an X-class flare, the most intense category of solar flares. The European Space Agency said such flares can release as much energy as a billion atomic bombs. The Space Weather Prediction Center noted that flares of this strength are rare but not unprecedented. These solar flares can trigger geomagne

The Sun emitted a strong solar flare on Jan. 18, peaking at 1:09 PM ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9. https://go.nasa.gov/4pMKbLQ Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground. However — when intense enough — they can disturb the atmosphere in the layer where GPS & communications signals travel. To see how such space we
