A total solar eclipse can be seen from Earth today, blotting out the Sun over Southeast Asia and parts of the Pacific Ocean. Brush up on the science behind this spectacular event: | TED-Ed

The Sun emitted a strong solar flare on Nov. 30, 2025, peaking at 9:49 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.9 class: go.nasa.gov/4alXf6P 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 sp

How much damage could a powerful solar flare actually do—and are we ready for it? Two days ago, a massive solar flare erupted. If it had been facing Earth, it likely would’ve registered as a G5—the highest level on NOAA’s geomagnetic storm scale. That’s Carrington Event territory. This isn’t a prediction. It’s just science. And understanding science isn’t fear-mongering. A G5 could cause: Widespread electrical disruptions Major blackouts Internet and communication systems offline And let’s be ho
