What Happens During a Total Solar Eclipse

A solar eclipse happens when the Moon moves directly between Earth and the Sun, covering the Sun and casting a narrow region of Earth into darkness.

When the Sun's brilliant surface is hidden, its faint and wispy atmosphere becomes visible. Stars and planets can emerge in the darkened sky, temperatures can fall, and winds may strengthen. Birds and insects may even begin behaving as though night has arrived.

On August 12, 2026, a solar eclipse will be visible across a large part of Europe. The narrow path of totality, where the Moon completely covers the Sun, will pass across Greenland, Iceland, a small part of northeastern Portugal, and then Spain.

Elsewhere in Europe, observers will experience a partial solar eclipse. In these locations, the Moon will appear to take a 'bite' out of the Sun, causing daylight to dim slightly.

ESA Will Broadcast the Eclipse Live From Spain

ESA will mark the event with a live broadcast from the Observatorio Astrofísico de Javalambre in Teruel (Spain). Spain is expected to provide excellent conditions for viewing as the eclipse moves across the country from west to east.

Viewers can tune in through ESA Web TV or ESA's YouTube channel beginning at 1:30 p.m. EDT (19:30 CEST) on August 12.

Award-winning space scientist and science communicator Dame Dr Maggie Aderin will host the broadcast. Guests will include ESA's Director of Science Professor Carole Mundell, ESA scientists Andy To, Miho Janvier and Martin Hewitson, and observatory director Javier Cenarro.

Live interviews, explanations and striking imagery will explore several aspects of eclipse science. Topics will include the Sun and its corona, the famous eclipse that helped transform our understanding of gravity, and ESA's work to create artificial solar eclipses in space.

81 Seconds of Total Darkness

The main event will occur at 2:31 p.m. EDT (11:31 a.m. PDT) when Javalambre experiences 1 minute and 21 seconds of totality. During that brief period, the Moon will completely cover the Sun and send the observatory into darkness.

Coverage will include telescope views and drone footage of the eclipse, along with Maggie and Carole's reactions as they witness the event.

The broadcast will be presented in English and is expected to finish at about 2:45 p.m. EDT (11:45 a.m. PDT).

Why Javalambre Is an Ideal Eclipse Viewing Site

The Observatorio Astrofísico de Javalambre is a world-class astronomical facility positioned directly within the path of totality. Its two main professional telescopes carry out wide-sky astronomical surveys that help scientists investigate galaxies, dark energy, and the large-scale structure of the cosmos.

The observatory is also well suited for eclipse viewing. Cloud cover is uncommon, light pollution is low, and the site has an especially clear view toward the western horizon. That will be important because the Sun will be moving toward sunset as the Moon passes in front of it.

Several additional small telescopes will be brought to the observatory specifically for the eclipse. Their live feeds will provide continuous close-up views as the Moon gradually moves across the Sun, showing the different stages of the event.

During the broadcast, Javier Cenarro, Director of the observatory, will discuss Javalambre and explain its significance for a future ESA space science mission.

Multiple Live Feeds Will Track the Eclipse

ESA will not rely only on observations from Javalambre. Two additional live feeds will come from other locations inside the path of totality, improving the chances that the broadcast will capture clear, high-quality views of the eclipse.

One feed will come from ESA's public event in León. Another will originate in Frómista (Palencia), where collaborator Alejandro Sánchez de Miguel will conduct eclipse observations. He is affiliated with the Institute of Astrophysics of Andalusia, the Complutense University of Madrid, and the Stars4All Foundation.
