AI Insight
On Wednesday 12 August, a total solar eclipse will be visible across Greenland, Iceland, northeastern Portugal and Spain, marking the first total eclipse visible from mainland Spain since 1905. During a total solar eclipse, the Moon passes between Earth and the Sun, casting a shadow on Earth's surface that allows observers in the darkest part to see the Sun's corona as its face is completely blocked. The European Space Agency will provide a live broadcast from the Observatorio Astrofísico de Javalambre and coordinate public viewing events including workshops and observations in León, Spain.
Why it matters
This rare astronomical event provides both scientific observation opportunities and public engagement with celestial phenomena. The ESA's live broadcast and organized events will make the eclipse accessible to global audiences and local communities, promoting public understanding of astronomy.

When the Moon passes between Earth and the Sun, it casts a shadow onto Earth’s surface. For people in the darkest part of this shadow, the face of the Sun is totally blocked out, and its wispy atmosphere becomes visible.
On Wednesday 12 August, such a shadow will cross Greenland, Iceland, northeastern Portugal and Spain. With this being the first total eclipse visible from mainland Spain since 1905, the European Space Agency (ESA) has decided to do something special.
ESA’s live broadcast from the Observatorio Astrofísico de Javalambre will allow anyone to experience this rare phenomenon from anywhere in the world. Meanwhile, the Agency is working with the City and University of León to organise a free in-person event, inviting people to come together for a day of interactive workshops, talks and live observations.
