Total Solar Eclipse Crosses Europe and Arctic on August 12

The 2026 total solar eclipse, a rare celestial event that cast a shadow across parts of the Northern Hemisphere on August 12, provided a spectacular show for skywatchers and a wealth of data for scientists. The moon's dark central shadow, or umbra, traced a narrow path from Arctic Russia through Greenland, Iceland, and Spain, with a brief touch on Portugal, offering up to 2 minutes and 18 seconds of totality for those directly in its track.

The event was the first total solar eclipse visible from Europe since 2006 and the first to cross Spain since 1905. Observers within the path of totality witnessed a dramatic transformation of the landscape into a false twilight as the moon completely obscured the sun. This allowed the sun's faint outer atmosphere, the corona, to become visible to the naked eye. Photographers captured stunning images of the corona's plasma streams and a prominent solar prominence, a loop of plasma arcing from the sun's surface, visible as a fiery red feature on the sun's edge.

From space, the eclipse was observed as a planetary-scale event. Satellite imagery from geostationary weather satellites and deep-space observatories revealed the moon's shadow as a...
