A total solar eclipse began Wednesday, as the Moon moved directly across the Sun to block sunlight over parts of Europe [1, 2].
This event marks the first time a total solar eclipse has been visible from parts of mainland Europe in nearly three decades, having not occurred since 1999 [5].
The path of totality, the region where the Sun is completely obscured, crossed through Spain, Portugal, Iceland, Greenland, and northern Russia [3, 4]. Millions of people gathered across these regions to witness the phenomenon [3].
Astronomers said that the event occurred because the Moon moved between the Earth and the Sun [1, 6]. This alignment cast a shadow that completely blocked the Sun's light for those positioned within the path of totality [1, 6].
While the total eclipse was limited to a specific geographic corridor, the broader event had a massive reach. Approximately one billion people experienced either partly or fully dark skies during the transition [6].
In northern Spain and Iceland, observers used specialized solar glasses to watch the Moon gradually cover the solar disk [1, 3]. The event drew global attention as viewers tracked the shadow's movement across the Atlantic and into the European continent [3].
“The first total solar eclipse visible from parts of mainland Europe in almost three decades.”
The 2026 eclipse serves as a significant astronomical milestone for Europe, ending a 27-year gap in mainland totality. Because total solar eclipses occur at specific coordinates infrequently, such events drive massive temporary migrations of 'eclipse chasers' and researchers, providing a rare opportunity to study the solar corona and atmospheric changes in the European hemisphere.
