For the first time in 121 years, mainland Spain will fall under the shadow of a total solar eclipse. On 12 August 2026, the Moon will slide directly in front of the Sun, turning day into twilight across a strip of the country. The last time this happened from Spanish soil was 1905.
The path of totality will cross Greenland, Iceland, Spain and a small part of northeastern Portugal. Other parts of Europe will see only a partial eclipse. Spain gets the largest area of totality in Europe, with the shadow moving from west to east and continuing over the Balearic Islands. This eclipse is the first of three solar eclipses visible from Spain between 2026 and 2028.
Why this eclipse matters to scientists and the public
The European Space Agency is organizing a range of activities around the event. ESA will host a live broadcast from the Observatorio Astrofísico de Javalambre in Teruel, a top-class astronomical facility inside the band of totality. Experts will explain the science behind the eclipse and its wider relevance. The broadcast will be available in English via ESA Web TV and YouTube. It will be hosted by Dame Dr. Maggie Aderin, an award-winning space scientist and science communicator.
During a total solar eclipse, the Moon passes directly in front of the Sun, blocking most of its light and allowing viewers to see the Sun’s fiery atmosphere. It is an impressive spectacle, last visible from mainland Europe in 2006.
A shared moment across Europe
The eclipse represents a unique moment for millions of people across Europe to witness this rare natural phenomenon together. It also offers a chance to experience first-hand the leading solar and space science underway in Europe. ESA missions studying the Sun and its interaction with Earth include Solar Orbiter, Smile and Proba 3.
Professor Carole Mundell, ESA Director of Science, said a total solar eclipse is one of those rare moments when millions of people can look up together and feel both wonder and curiosity. She said it is a shared moment that connects us to the Universe and reminds us that the desire to explore and understand is one of humanity’s greatest strengths. She added that ESA uses moments like this to bring space science and technology closer to society, to inspire future generations and bring people across Europe together through the excitement of discovery.
For Spain, the 2026 eclipse is not just a scientific event. It is a rare chance for a country to watch the sky go dark in the middle of the day, something no living Spaniard has seen from the mainland.
