Total solar eclipse 2026 (Official ESA broadcast)

The European Space Agency (ESA) will host a live broadcast from the Observatorio Astrofísico de Javalambre in Spain during the total solar eclipse on 12 August 2026. The eclipse’s path of totality will traverse Greenland, Iceland, Spain, and a small part of northeastern Portugal, while most of Europe will observe a partial eclipse. The event will feature live telescope views, expert commentary, and insights into solar science and space weather. The broadcast aims to engage the public with real-time observations and discussions led by scientists and ESA representatives.

A total solar eclipse occurs when the Moon aligns directly between Earth and the Sun, fully obscuring the Sun’s face for viewers within the path of totality. The Observatorio Astrofísico de Javalambre, located in Spain’s path of totality, will serve as the primary broadcast site. Scientists, astronomers, and guests will explore the scientific significance of eclipses, their role in advancing space science, and their broader implications for Earth’s environment. The event will also highlight ESA’s ongoing research and activities related to solar observations and space weather monitoring.

The broadcast will be hosted by Dame Dr Maggie Aderin, a space scientist and science communicator, alongside ESA’s Director of Science Carole Mundell. Additional guests will include experts in solar physics and astronomy, who will provide live commentary and interviews throughout the eclipse. Viewers can expect behind-the-scenes coverage from the observatory, including technical preparations and real-time observations. The program will also feature discussions on ESA’s missions and instruments designed to study the Sun and its influence on space weather.

This live broadcast offers a rare opportunity for the public to witness a total solar eclipse while gaining insights into solar science and ESA’s research efforts. The event underscores the importance of international collaboration in space science and public engagement with astronomical phenomena. ESA’s coverage will be accessible to a global audience, providing educational content and live demonstrations of eclipse observations.
