Book "Eclipses of the Sun. Los eclipses españoles de 2026, 2027 y 2028" of the National Geographic Institute

An essential guide to the upcoming eclipses in Spain

Between 2026 and 2028, Spain will experience a historic astronomical trilogy: two total solar eclipses and one annular eclipse visible from different points of our geography. This has not happened for more than a century, and it will be a unique occasion for millions of observers. The book "Eclipses of the Sun. Los eclipses españoles de 2026, 2027 y 2028", published by the National Geographic Institute (IGN), is the official guide to understand, prepare and enjoy these celestial phenomena with all the necessary safety and scientific rigor.

Science and popularization within everyone's reach

The volume has been prepared by a team of astronomers from the National Astronomical Observatory, coordinated by Rafael Bachiller, and combines technical precision with a clear and accessible style. From the first pages, the reader finds didactic explanations about what an eclipse is, why they occur, the different types (total, annular and partial) and how they are observed from Earth. Thanks to its pedagogical approach, the book is useful for both beginner amateurs and experienced astronomers who wish to delve deeper into the Sun-Earth-Moon dynamics.

Exclusive maps, schedules and predictions

One of the strengths of this work is the inclusion of detailed maps, graphs and visibility tables showing how the eclipses will be seen from each province and autonomous city in Spain. These data come directly from the official calculations of the National Astronomical Observatory, which makes this guide an essential reference for planning any trip or observing activity.

The eclipse in science and history

The book also traces the cultural and scientific history of eclipses, showing how they have inspired awe and fascination over the centuries. From records in Egypt and Mesopotamia to major scientific milestones, such as the experimental validation of Einstein's theory of General Relativity in 1919, eclipses have been the protagonists of key moments in the evolution of human knowledge. The reader will discover stories about Columbus, Charlemagne, Edmond Halley and other historical figures who observed and documented these events.

Artistic and mythological fascination

Beyond science, eclipses have had a great impact on culture. The book collects examples of their representation in art, literature and popular legends: from myths about sun-devouring dragons to pictorial works by artists such as José de Ribera. This interdisciplinary approach turns the work into a journey that connects science, history and art.

Practical tips for enjoying the show

The book devotes an essential section to the safe observation of eclipses. It explains the correct use of eclipse glasses and certified solar filters, as well as alternative projection methods. It also includes guidelines for astrophotography, offering recommendations for capturing spectacular images without compromising the safety of equipment or eyesight.
