Scientists spot warning signs hours before sun’s most powerful flare
A recent observation has revealed the prelude to one of the sun’s most powerful flares, captured in unprecedented detail. According to a study posted on arXiv, researchers led by Louis Seyfritz at the New Jersey Institute of Technology recorded telltale signs of anX9-class solar flare hours before it erupted,
The sun is an incomprehensibly gigantic, constantly roiling nuclear furnace—but some days are even busier than others. Based on data collected by NASA’s Solar Dynamics Observatory, our solar system’s central star recently fired off not one,

Three flares from sunspot region 4455 — M9.3, M7.7, and X1.0 — fired off in roughly 10 hours and lit up Earth-directed CMEs
Three solar flares from sunspot region 4455, classified at M9.3, M7.7, and X1.0, erupted within roughly 10 hours on June 3, 2026, each launching a coronal mass ejection aimed at Earth. The rapid-fire sequence prompted NOAA’s Space Weather Prediction Center to issue a Strong (G3) geomagnetic storm watch for June 4 and 5 UTC,
Talk about a heated situation. The sun unleashed two colossal solar flares within seven hours of each other this week, triggering radio blackouts across parts of Earth. Solar flares are strong, powerful explosions of energy that have the potential to wreak ...
Our sun is a roiling mass of energy, with solar flares exploding on its surface, sending gas, plasma, and light that blasts across the solar system. When radiation from extra-powerful flares breaks through Earth's outer protective magnetosphere, it can ...
