The U.S. will experience a total solar eclipse in 2017 for the first time in over 20 years. The last total solar eclipse took place in 1991 and was only visible from Hawaii.
The eclipse occurs when the moon passes between the Earth and the Sun blocking out the sunlight. In 2017, the total solar eclipse will be visible through a narrow corridor that spans different towns and cities in 9 states – Oregon, Idaho, Wyoming, Nebraska, Missouri, Kentucky, Tennessee, Georgia and South Carolina.
