How to Safely Watch a Solar Eclipse | European Space Agency

A total solar eclipse becomes visible across parts of Europe on August 12, 2026. The path of totality will sweep across Greenland, Iceland, Spain and a small area of northeastern Portugal, while much of Europe will experience a partial eclipse.

A total solar eclipse occurs when the Moon passes directly between Earth and the Sun, completely blocking the face of the Sun.

A solar eclipse is an unforgettable sight, but only if you watch it safely!

European Space Agency (ESA) reserve astronaut Sara García Alonso shows you how to enjoy this incredible cosmic event using certified eclipse glasses and explains why ordinary sunglasses are not enough.

Learn what happens during the stages of an eclipse, when it is safe to look up, and how to experience one of the greatest shows in the Solar System without risking your eyes.
