Exactly one year from today, Europe will experience its first total solar eclipse in 20 years.

The full eclipse will be visible in parts of Greenland, Iceland, Spain, Russia, and a small area of Portugal; meanwhile, a partial eclipse will occur over much of Europe, Africa, North America, the Atlantic Ocean, Arctic Ocean and Pacific Ocean, NASA said.
