Portugal Witnesses First Total Solar Eclipse Since 1912

Portugal is set to witness its first total solar eclipse since 1912 on Wednesday, August 12, 2026, with the full eclipse visible only in a small area of the Montesinho Natural Park in Bragança, in the country’s northeast. According to the Saudi Press Agency (SPA), the total phase of the eclipse will last approximately 26 seconds in this region, while a partial eclipse will be visible across the rest of the country, with the sun obscured by 92% to 99% on the mainland and 74% to 77% in the Azores and Madeira.

Context and Background

This rare celestial event marks the first total solar eclipse to cross Portuguese territory in over a century. The last total eclipse visible from Portugal occurred in 1912, making this a significant astronomical milestone. The eclipse is scheduled to begin at approximately 18:30 local time, reach its maximum at around 19:30, and conclude by 20:30, spanning a total duration of about two hours.

The path of totality, where the moon completely blocks the sun, passes through the Montesinho Natural Park, a pristine area known for its biodiversity and dark skies, making it an ideal location for astronomical observation. The park is expected to attract thousands of visitors, including scientists, amateur astronomers, and tourists from around the world.

Key Details

To facilitate public viewing, several Portuguese astronomical observatories, municipalities, associations, and the ‘Ciência Viva’ science centers are organizing observation sessions across the country. These events will feature telescopes equipped with solar filters and certified protective glasses to ensure safe viewing. The SPA report emphasizes that these measures are crucial to prevent eye damage during the eclipse.

According to the SPA, the next total solar eclipse visible from Portugal will not occur until 2144. This underscores the rarity of the event and the importance of maximizing the opportunity for scientific research and public education. Astronomers will use advanced instruments to study the sun’s corona, which is only visible during a total eclipse, providing valuable data for solar physics research.

Implications and Impact

The eclipse has significant implications for scientific research and public engagement. Total solar eclipses offer unique opportunities to study the sun’s outer atmosphere and to test theories of general relativity. International research teams are expected to deploy portable instruments to capture high-resolution images and data. Additionally, the event is likely to boost local tourism, providing an economic boost to the Bragança region and showcasing Portugal’s commitment to science and education.

From an international perspective, the eclipse is a reminder of the wonders of the universe and the importance of international cooperation in space and astronomical research. Saudi Arabia, through its Vision 2030, aims to foster a culture of scientific inquiry and innovation. The Kingdom has invested heavily in space programs and scientific research, aligning with global efforts to explore and understand cosmic phenomena.

Vision 2030 Alignment

This celestial event underscores the importance of investing in science and education, key pillars of Saudi Arabia’s Vision 2030. The Kingdom’s own ambitious space programs, including the recent astronaut missions and satellite launches, demonstrate its commitment to advancing human knowledge and contributing to global scientific endeavors. As the world looks to the skies, Saudi Arabia is positioning itself as a leader in the region, encouraging its youth to pursue careers in science, technology, engineering, and mathematics (STEM). The total solar eclipse in Portugal serves as a reminder of the wonders that science can unlock and the role that Saudi Arabia plays in promoting such global exploration and discovery.
