What is a Solar Eclipse?

A solar eclipse is one of nature’s most breathtaking spectacles. It happens when the Moon passes between the Earth and the Sun, casting a shadow that temporarily blocks the Sun’s light. Depending on where you are, this can create a total eclipse - where the Sun is completely hidden, or a partial eclipse - where only part of the Sun is covered. During a total eclipse, day briefly turns to night, stars may appear in the sky, and the Sun’s outer atmosphere (the corona) becomes visible - a phenomenon so rare and awe- inspiring that people travel the globe to witness it.

“12 August 2026 – The Solar Event of a Generation”

Why August 12th, 2026 is Monumental

On 12th August 2026, Europe will experience one of the most remarkable celestial events of the century...

Special Note (Sunset Eclipse):

By the time the 2026 eclipse reaches Spain, evening will have arrived across the country. By the time totality comes to the Mediterranean, the Sun will be close enough to setting that it affords eclipse chasers in the Balearic Islands the relatively rare opportunity to witness a "sunset eclipse." It's not that a sunset eclipse itself is rare. Every total solar eclipse begins somewhere on Earth at sunrise and ends somewhere else on Earth at sunset. But considering that most of the planet's surface is covered by water, it's not often that the path of totality just happens to begin or end on land.

• It’s the first major European eclipse of the 21st century to be widely visible across the continent. For the UK, it will be the most significant eclipse since 1999, drawing nationwide excitement.

• For Spain and Portugal, tourism boards are already preparing for hundreds of thousands of visitors to witness the rare spectacle.

• Total Eclipse Path – In parts of Spain, Portugal, and Iceland, viewers will witness the full glory of totality, with the Sun disappearing entirely for several unforgettable minutes.

• UK Visibility – Across the United Kingdom, millions will see a partial eclipse of up to 95% totality, with the Sun dramatically obscured, creating a once-in-a-lifetime viewing opportunity.

This eclipse isn’t just an astronomical event - it’s a shared cultural moment, uniting families, schools, tourists, and communities in a collective experience of wonder.
