On the evening of August 12, 2026, an extraordinary celestial event is on the horizon: A total solar eclipse will pass over parts of Europe—though not over Germany.
Here in Germany, we will experience an impressive partial eclipse, which will nonetheless offer a rare and spectacular sight. Germany will be entirely within the Moon’s penumbra. As a result, the sun will not be completely, but clearly and visibly “nibbled away.”
What do you need to safely observe the solar eclipse? You can find a list 👉 here!
