A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially.Such an alignment occurs approximately every six months, during the eclipse season in its new moon phase, when the Moon's orbital plane is closest to the plane of Earth's orbit.

Adding people who travelled to the path of totality, an estimated 50 million people experienced the total solar eclipse. [9] Meanwhile, about 652 million people experienced a partial solar eclipse. [6] This eclipse was the first total solar eclipse visible from Canada since August 1, 2008, and from the provinces since February 26, 1979.
A stovetop pressure cooker. A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure.
The eclipse was part of Saros series 136, descending node, as was the solar eclipse of July 11, 1991, which was slightly longer, lasting up to 6 minutes 53.08 seconds (previous eclipses of the same saros series on June 30, 1973, and June 20, 1955, were longer, lasting 7 min 03.55 and 7 min 07.74, respectively).
An eclipse season is the only time when the Sun (from the perspective of the Earth) is close enough to one of the Moon's nodes to allow an eclipse to occur. During the season, whenever there is a full moon a lunar eclipse may occur and whenever there is a new moon a solar eclipse may occur.
