A total solar eclipse swept across parts of Europe on Wednesday, bringing millions into the streets and onto rooftops to witness a celestial event that won't return to the continent for generations. Maximum totality occurred off Iceland's west coast before the spectacle reached a small patch of Portugal and then Spain, ending in the Mediterranean.
The moon passed between the sun and the Earth, casting its shadow across a narrow swathe of the planet. Many parts of Greenland, Iceland and northern Spain experienced totality, while millions of Europeans across western Europe saw a partial eclipse. The umbra, or moon's sun-blocking shadow, took 1.5 hours to race along the 8,260-kilometre course, most of it over the Atlantic.
A Once-in-a-Lifetime Experience
Totality lasted up to 2 minutes and 18 seconds starting near the North Pole around Siberia in Russia before tracking south. Daytime darkness descended across the Iberian Peninsula, plus slivers of Greenland and Iceland. In the UK, more than 90% of the sun was covered by the moon for most parts.
Jake Foster, an astronomer at the Royal Observatory Greenwich, said: "From here in the UK, we're going to actually be very fortunate. We are seeing a partial eclipse, but it is a very strong partial, between 90 and 95%, depending on where you are in the UK. It's going to be happening around sunset. It is the golden hour eclipse, so it's going to be low on the western horizon. If you want to see the full eclipse, you need to get into the path of totality. And to get into the path totality, you're going to need to go to places like Greenland, Iceland, and northern Spain. Those are the places where the moon's shadow will be at its darkest, and you'll get that absolute 100% coverage of the moon in front of the sun."
He also said: "Well, in order to see a total solar eclipse from the very same location more than once, you could be waiting over 200 years for that to happen. Partial eclipses can be slightly more common. But again, if we're talking about just from one particular country or one particular region of a country, you might get lucky; you might have a few partial eclipses in a decade. However, they can be very rare depending on where you are."
Spain's last full solar eclipse, not counting the Canary Islands, occurred 114 years ago in 1912.
Public Gatherings and Safety Warnings
Foster said the safest way to view the eclipse directly is with solar eclipse glasses that have special lenses blocking out 99.9999% of the sun's light and are ISO certified. Without them, staring directly at the sun, even if just a slither of light remains, could damage eyesight.
In London, the historic Royal Observatory Greenwich hosted a watch party from its terraces and live streamed the event, weather permitting, as the sun was obscured over the city's skyline. Across Europe, astronomy shops saw a last-minute rush for certified viewing equipment. At one specialist store in Paris, customers queued for more than two hours to get eclipse glasses and binoculars.
One customer, 27-year-old Simon Noé, who works in video game research, said: "Two hours! Two hours for a pair of sunglasses," and added: "But for me, the eclipse is kind of a big deal. I remember when I was a child, I thought, What, there won't be another eclipse before 2026? 2026 seemed so far away. So this is a bit about making my inner child happy."
Scientific Observation
Two of ESA's space telescopes observed the eclipsed sun and its corona, or outer atmosphere. Proba-3, the space agency's artificial eclipse-making satellite duo, was positioned poorly but tried to sneak in some before-and-after shots.
Why This Matters:
This eclipse represents more than a celestial spectacle — it's a rare moment of collective wonder that transcends borders and brings communities together. The queues outside Paris astronomy shops and the watch parties from Greenwich to Reykjavik show how shared experiences of nature can unite people across Europe at a time when division often dominates headlines. For Spain, this is the first total eclipse visible from the mainland in over a century, connecting generations across time. The scientific observations by ESA's telescopes also demonstrate Europe's continued investment in space research and public science education. Events like this remind us that some experiences — a darkened sky at midday, two minutes of totality — belong to everyone equally, regardless of nationality or circumstance. They're bucket list moments that make inner children happy, as one Parisian put it, and they won't come again for lifetimes.
