Millions of people across Europe are preparing to look up as a rare total solar eclipse crosses the continent, briefly turning day into night. The celestial event, which begins in Russia's remote Arctic north, will then cast its shadow over parts of Greenland and Iceland before reaching mainland Europe.
Spain is the focal point of excitement, with tourists flocking to normally quiet villages along the narrow path of totality that stretches from the northern Atlantic coast to the Mediterranean. This is the first total solar eclipse on mainland Europe in two decades, and the first in Spain in over a century. Reykjavik, Iceland, has not experienced one since 1433.
The eclipse will be visible in its full glory only in a handful of locations, with the key viewing times being Reykjavik at 17:48 local time, León at 20:28, Zaragoza at 20:29, and Valencia at 20:32. For millions more across Europe, Canada, the northern United States, and northwest Africa, a partial eclipse will be visible, driving high demand for special viewing glasses.
A fleeting spectacle
Throughout history, eclipses have inspired awe and reverence, as they seem to pause the natural order. The umbra, or shadow, cast by the alignment of the Sun and Moon creates an eerie twilight, causing temperatures to drop, shadows to shift, and some animals to settle down for the night. But the phenomenon is brief: in parts of Russia and Greenland, totality lasts under two and a half minutes, and in Spain, it will be less than two minutes just before sunset. The partial phase, which occurs as the Moon crosses the Sun's path, will last about an hour and 45 minutes.
Scientists are eager to study the Sun's atmosphere and its outermost layer, the corona, during this rare opportunity. The event will be livestreamed by NASA and the European Space Agency, offering researchers a chance to learn more about solar winds and the Sun's magnetic field.
Weather worries and clear skies
Clouds are the eternal enemy of eclipse-chasers, and forecast rain could spoil the view in Iceland's Westfjords region. Saevar Helgi Bragason, a scientist and astronomer in Reykjavik, expressed mixed emotions, saying he felt "both excitement and heartbreak" due to the unfavorable forecast. "It's almost like I've lost someone," he told AFP, though he hoped the skies would clear just long enough to witness "the shortest, most sudden, most beautiful, most unique and, hopefully, most memorable and beautiful nighttime of our life."
Spain, however, is expected to enjoy clear skies, though high temperatures above 35°C and the risk of wildfires remain concerns. The country is bracing for an economic boost, with predictions that over 446,000 extra tourists could bring €347 million to the local economy. British astrophysicist Graham Jones, speaking from Fontanil de los Oteros in northern Spain, highlighted the uniqueness of the event: "The path of totality is very narrow. It's only a couple of hundred kilometres wide. That's what's so special about Spain. The path of totality really goes across the Spanish peninsula."
As the eclipse approaches, Europe braces for the rare spectacle, with eclipse glasses selling out and exact times for Spanish cities being widely shared. For those unable to see it in person, a curated soundtrack offers a way to mark the moment. The event is a reminder of the wonders of the cosmos and the shared experience of gazing at the sky.
