The Dynamic Surface of the Sun in Hydrogen-Alpha

On March 22, 2025, I captured this high-resolution image of the Sun from Dubai using a dedicated hydrogen-alpha solar telescope. The image reveals intricate surface details, including solar filaments, active regions, and dramatic prominences rising from the solar limb. For scale, a small Earth icon is included to highlight the immense size of our star.

Hydrogen-alpha imaging allows us to witness the dynamic and ever-changing nature of the Sun’s chromosphere, offering a glimpse into solar activity that affects space weather and our technological systems on Earth.
