A total solar eclipse is occurring today, Aug. 12, 2026 [1], as the Moon passes directly between the Earth and the Sun [4].
This astronomical event allows scientists and the public to observe the solar corona and study the effects of sudden darkness on the environment. Because the path of totality is narrow, millions of people outside the direct line are relying on live digital transmissions to view the event.
The eclipse is visible as a total solar eclipse in several regions, including Spain, Iceland, Greenland, northern Russia, and northeast Portugal [3]. In Spain, cities such as Segovia are positioned within the path of totality [2].
Other regions are experiencing a partial eclipse. In Málaga, Spain, the Moon is expected to cover up to 94.7% of the solar disc [5]. This high percentage creates a significant dimming of daylight, though it does not reach the complete darkness of a total eclipse.
While the event is a major focal point across Europe and the Arctic, it is not visible in all parts of the world. Chile, for example, remains outside the zone of totality [5].
Observers are reminded that looking directly at the sun without specialized eye protection can cause permanent retinal damage. NASA and other space agencies are providing live streams for those outside the path of totality or in areas with cloud cover [1].
“The Moon will pass directly between the Earth and the Sun, casting its shadow on the Earth's surface.”
Total solar eclipses are rare for any single geographic location, making the 2026 event a significant data-gathering opportunity for solar physicists. The specific trajectory across the Arctic and Europe allows for the study of atmospheric changes in different climates simultaneously, while the availability of high-definition live streams democratizes access to an event that is physically restricted to a narrow corridor of the Earth's surface.
