🌍🌑 The path of totality will cross Russia, Greenland, Iceland and the Atlantic before reaching Spain and a small part of Portugal.
A partial eclipse will be visible across wider areas of Europe, North America and northern Africa.

What links the 1959 eclipse to the rise of astrophysics in the Canary Islands?
The “end of the world” eclipse drew scientific expeditions to the islands and coincided with the first steps towards the Canarian observatories.
