On Aug. 2, 2027, a total solar eclipse will be visible from a broad path sweeping across the Atlantic Ocean, Southern Europe, North Africa and the Middle East. A total solar eclipse occurs when the moon moves in front of the sun while it's slightly larger in apparent size so that the moon completely covers the sun's disk. The path of totality will measure a maximum of 160 miles (258 kilometers) wide, and it will cross Morocco, Algeria, Tunisia, Libya, Egypt, Sudan and Saudi A
