Powerful Solar Storms Illuminate Earth’s Sky with Dazzling Auroras
A powerful solar storm in mid-November 2025 triggered bright auroras across the Northern Hemisphere. Astronauts on the International Space Station took extra precautions against radiation bursts.
The storm originated from sunspot AR4274. It unleashed huge coronal mass ejections (CMEs). These CMEs carried heavy, radioactive ions. This poses a risk to astronauts in orbit.
Safety Measures on ISS
The station’s Destiny laboratory offers extra shielding. Three Russian cosmonauts were advised to spend the night there. US and Japanese crew members remained in their usual quarters. Flight controllers also identified modules to avoid during the storm .
Radiation Risk and Earth’s Protection
Earth’s magnetic field and atmosphere block most dangerous radiation. This makes intense solar storms relatively safe for people on the ground. However, astronauts in orbit face exposure risks, highlighting the need for precautions.
Aurora Spectacle
The solar storm created spectacular auroras, visible across the Northern Hemisphere, showcasing the awe-inspiring power of space weather.
