A solar eclipse is happening on Wednesday, August 12, 2026. Learn where you can see it.

A total solar eclipse is on the horizon. On Wednesday, August 12, 2026, over the Arctic Ocean and western Europe, to be precise.

For astronomy fans, the best views will be found in Greenland, Iceland, and Spain.  For Canadians, a “bite-sized” partial solar eclipse will be most visible in northern and eastern locations – with a 50 percent solar eclipse visible in St. John’s, Newfoundland and Labrador, and a 61 percent eclipse in Iqaluit, Nunavut. Icelanders are particularly excited: this is the first solar eclipse in the capitol of Reykjavik since June 17, 1433!

A solar eclipse occurs when the moon passes between the Earth and the Sun, blocking the Sun’s rays from reaching the Earth. The shadow cast by the moon is called the path of totality. For observers within the path of totality in Iceland and Spain, the moon will completely blot out the sun, the sky will darken, and the air will become colder. Outside of the path of totality, observers can potentially see a partial solar eclipse depending on where they are on the globe. NASA provides a list of cities where the eclipse will be visible; the list includes both when the eclipse occurs and how much of the Sun will be obscured.

Remember – a partial solar eclipse is not safe to look at with the naked eye. Use eclipse safety glasses to protect your eyes; or, get crafty and follow NASA’s instructions for creating a pinhole projector. Happy eclipse viewing! 

À propos de l’IP

L'Institut Périmètre est le plus grand centre de recherche en physique théorique au monde. Fondé en 1999, cet institut indépendant vise à favoriser les percées dans la compréhension fondamentale de notre univers, des plus infimes particules au cosmos tout entier. Les recherches effectuées à l’Institut Périmètre reposent sur l'idée que la science fondamentale fait progresser le savoir humain et catalyse l'innovation, et que la physique théorique d'aujourd'hui est la technologie de demain. Situé dans la région de Waterloo, cet établissement sans but lucratif met de l'avant un partenariat public-privé unique en son genre avec entre autres les gouvernements de l'Ontario et du Canada. Il facilite la recherche de pointe, forme la prochaine génération de pionniers de la science et communique le pouvoir de la physique grâce à des programmes primés d'éducation et de vulgarisation.
