A rare total solar eclipse will sweep across Spain, Iceland and Greenland on August 12, marking the first total solar eclipse visible from mainland Spain since 1905 and the beginning of a remarkable series of celestial events over the next two years, according to The Associated Press. The eclipse will begin near the North Pole before tracking south across the Atlantic Ocean. Totality, when the moon completely blocks the sun, will last up to 2 minutes and 18 seconds, with the longest duration occurring off Iceland’s west coast. By the time the eclipse reaches mainland Spain near sunset, totality will last about one minute before ending over the Mediterranean Sea. Millions of people across Europe, North America and West Africa will also witness a partial solar eclipse, with the moon obscuring much of the sun in many locations.
