A total solar eclipse occurs when the moon completely blocks the Sun, revealing the Sun’s beautiful outer atmosphere known as the corona.
The path of totality will only be visible in parts of the southern pacific Ocean, central Chile, and central Argentina. When it makes landfall, it’s going to zip by pretty quickly. To experience several minutes of totality, you’ll have to be in a boat in the deep south pacific. A partial eclipse will be visible in most parts of the southern Pacific Ocean and western South America.

Saturn rules the summer sky, but on this night, the ringed planet truly takes center stage. When it reaches opposition (its closest approach to the Earth), Saturn will be bright and fully illuminated by the Sun. You may even notice that its rings look brighter than usual thanks to a phenomenon known as the Seeliger Effect. Take it all in! Saturn’s rings will be visible in even small aperture telescopes.
A medium-sized or larger telescope will allow you to see Saturn’s rings and a few of its brightest moons.
A portion of the Moon will be fully darkened by Earth’s umbra (shadow). Visible throughout most of Europe, Africa, Central Asia, and the Indian Ocean.
