About the livestream
Tune into the live broadcast via ESA Web TV or ESA's YouTube channel from 19:30 CEST on 12 August.
The broadcast will be hosted by Dame Dr Maggie Aderin, award-winning space scientist and science communicator. It will feature ESA’s Director of Science Professor Carole Mundell, as well as ESA scientists Andy To, Miho Janvier and Martin Hewitson, and observatory director Javier Cenarro.
Through live interviews, explainers and spectacular imagery, viewers will discover topics ranging from the mysteries of the Sun and its corona, to how one famous eclipse changed our understanding of gravity, and how ESA is now creating artificial solar eclipses in space.
The highlight will be the coverage of 1 minute and 21 seconds of totality at 20:31 CEST, as the Moon plunges Javalambre into complete darkness. As well as telescope feeds and drone shots of the eclipse, we will capture Maggie and Carole’s responses to witnessing this extraordinary phenomenon.
Have a question about the eclipse? Send it in using #AskESA on Bluesky or X. A selection will be answered live during the broadcast. Find out more towards the end of this article.
The broadcast will be presented in English. It will end at about 20:45 CEST.
About the observatory
The Observatorio Astrofísico de Javalambre is a world-class astronomical observatory located within the path of totality. It mainly consists of two professional telescopes designed to carry out large-sky astronomical surveys that help astronomers study galaxies, dark energy and the structure of the cosmos.
Importantly, viewing conditions at the observatory are excellent, with cloud cover rare and light pollution low. The location offers a very clear view to the western horizon, where the Sun will be beginning to set as it is eclipsed by the Moon.
Additional small telescopes will be taken up to the observatory to observe the eclipse. A live feed from these telescopes at the observatory will provide continuous views as the Moon passes in front of the Sun, offering close-up observations of the different phases of the eclipse.
Javier Cenarro, Director of the observatory, will be interviewed during the live broadcast about Javalambre and its importance for a future ESA space science mission.
Continuous coverage of the eclipse during the broadcast
In addition to the telescope feed from Javalambre, ESA will receive live observations from two more locations within the path of totality, increasing the likelihood of including high-quality imagery in the live broadcast. One feed will originate from ESA’s public event in León, while the second will come from Frómista (Palencia), where our collaborator Alejandro Sánchez de Miguel, affiliated with the Institute of Astrophysics of Andalusia, the Complutense University of Madrid, and the Stars4All Foundation, will be carrying out eclipse observations.
Prefer to join us in person?
We are joining hands with the City of León and the University of León to organise a free public event at the Palacio de Exposiciones y Congresos de León. Most of this event will be in Spanish.
From 10:00–14:00 CEST, visitors can explore a wide range of hands-on workshops, experiments and interactive activities designed for all ages. In the late afternoon, the programme moves outdoors. Gates open at 17:30 CEST, giving visitors plenty of time to find a place before the main stage programme begins at 18:30 CEST.

Important: Looking directly at the Sun without proper protection can cause serious eye damage. Regular sunglasses are not safe for observing a solar eclipse. To watch the eclipse safely, always use certified eclipse glasses that meet the appropriate safety standards and wear them at all times during the partial phases. Only during totality – when the Moon completely covers the Sun – is it safe to briefly look without protection. As soon as the Sun begins to reappear, eclipse glasses must be worn again.
