Millions of people around the world will have a rare chance to witness the total solar eclipse occurring at an uncommon frequency of just seven years.
It is dubbed the Great North American Eclipse.
According to NASA, the last total solar eclipse occurred on August 21, 2017, with an estimated 215 million US adults (88 per cent of US adults) viewing it either directly or electronically.
A total solar eclipse, by definition, occurs when the moon's shadow covers the sun's rays entirely, plunging those in the shadow's path into darkness for a few minutes.
