Four Things to Know About the 2017 Solar Eclipse
Find out the basic when, where, and why of the next total solar eclipse.

How to Watch a Partial Solar Eclipse Safely
Can't make it to totality? All locations in the continental U.S. will see a deep partial solar eclipse — but don't gaze directly at the Sun during the partial phases. Here's what you can do instead to see the spectacle.

How to Look At The Sun
This observing guide to solar eclipses — partial and total alike — covers direct-viewing with solar-viewing filters, projected view, or viewing through a filter-equipped telescope.

Photos of Past Eclipses
S&T's readers often travel great distances to stand in the Moon's shadow and record the otherworldly spectacle taking place in the sky above them. Browse through their amazing images — then capture some of your own on August 21, 2017.
