A massive solar eruption was simultaneously recorded on Earth, the Moon, and Mars. ☀️ On October 28, 2021, the Sun let out a massive coronal mass ejection. It was so huge that it spread all the way to both Mars and Earth, even though they were on opposite sides of the Sun and about 250 million kilometers away from each other!

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
