And just like that, it's over.Total solar eclipses are incredible moments in time, but they are fleeting. As the moon passes directly in front of the sun and its shadow sweeps across Earth's surface, the temperature drops and the light takes on an eerie twilight quality. Birds and other animals go quiet. It's a spectacle unlike any other. And for millions today who were lucky enough to be in the path of totality across Greenland, Iceland and Spain, that's exactly what they experienced. "I cannot believe what I just witnessed. I knew what to expect — I've seen thousands of photos but nothing compares to that feeling you get when you watch the sun transform before your very eyes," Space.com skywatching editor Daisy Dobrijevic said after watching the eclipse from the deck of the MS Spitsbergen on the HX Expeditions eclipse voyage in Scoresby Sund, Greenland on Aug. 12, 2026.

The huge prominence was the icing on the cake," Dobrijevic added. "This is something I will never forget and I feel privileged to have experienced it in one of the most remarkable environments on Earth and alongside an incredible group of people aboard HX Expedition's MS Spitsbergen."The sun during a total solar eclipse as seen from deck of the MS Spitsbergen on the HX Expeditions eclipse voyage in Scoresby Sund on Aug. 12, 2026. (Image credit: Daisy Dobrijevic/Future)The 182 mile-wide (293-kilometer) path of totality — the line "drawn" on the face our our planet by the moon's shadow — began near Siberia over the Arctic Ocean and first arced down into eastern Greenland. From there, the path stretched across western Iceland and then into northern Spain where millions gathered to witness the spectacle. "It was the most incredible thing I've seen in my entire life," said Space.com skywatching writer Anthony Wood after witnessing the eclipse from Valoria la Buena, Spain alongside a team of citizen scientists from the Dynamic Eclipse Broadcast initiative. "It feels like it really shouldn't be happening. It strikes the lizard part of your brain that just tells you that this shouldn't be real."A total solar eclipse as seen in Valoria la Buena, Spain on Aug. 12, 2026.

Witnessing the crown-like shape of the corona stretching away from the dark shadow of the moon is one of the most breathtaking moments of an eclipse. Photographs don't do it justice, as they rarely do.A total solar eclipse is seen from San Millán de los Caballeros, Spain, Aug. 12, 2026.

Much of Canada got to witness the partial eclipse too, and so did Alaska.A total solar eclipse on Aug. 12, 2026 as seen from Segur de Calafell, Spain.

When this alignment happens, the moon casts its shadow along a line known as the path of totality. Only within this stripe will you be able to experience full totality.

This means that it's sometimes closer to Earth than other times. Total solar eclipses only occur when the moon is at just the right distance from Earth, making it appear the same size in the sky as the sun (or even slightly larger). This obscures the blinding light of the sun, allowing viewers to glimpse our star's outer atmosphere, or corona.The moon passes over the sun's horizon during a partial solar eclipse at Abbadia, le Château Observatoire in Hendaye, southwestern France, on Aug. 12, 2026. (Image credit: Philippe Lopez / AFP via Getty Images)When the moon is a bit farther away from Earth, it appears relatively smaller. And when solar eclipses fall on a date when the moon is at this greater distance from our planet, the moon doesn't completely block the sun. This creates what's known as an annular solar eclipse, or a "ring of fire" in the sky.A total solar eclipse is seen on Aug. 12, 2026 in the Riet Vell Nature Reserve in Amposta, Spain.

Looking farther out, the U.S. states of Montana, South Dakota, North Dakota, and areas of Canada will witness a total solar eclipse on Aug. 23, 2044. Submit your eclipse photos!
