This is a full view of the Sun in Hydrogen-alpha light, revealing a side of our star we can’t see with our eyes.

The surface isn’t calm—it’s alive. The grainy texture comes from hot gas constantly rising and falling. The dark patches are sunspots, where powerful magnetic fields tangle and twist, surrounded by brighter, more energetic regions. Multiple active regions (AR 3663–3666) are spread across the disk, adding to the Sun’s restless appearance.

Along the edge, you can see delicate, flame-like shapes lifting off the Sun. These are prominences—giant loops of glowing gas held up by magnetic forces. They may look small here, but each one can stretch tens of thousands of kilometres into space—large enough to swallow Earth many times over.
