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.

Sky & Telescope Eclipse Tours
Join Sky & Telescope in Kentucky to see this long-anticipated eclipse! Visit the U.S. Space & Rocket Center in Huntsville, Alabama, see Jack Daniel's Distillery in Lynchburg, Tennessee, and tour the Stones River National Battlefield. On the day of totality, we'll travel to the vicinity of Hopkinsville, Kentucky, near the point known as "greatest eclipse." (Greatest eclipse is when the axis of the Moon’s umbra passes closest to the center of the Earth.). Our carefully chosen site offers good viewing prospects along with all the amenities you'll need on a hot summer day.
Choose between two exciting options for a Sky & Telescope-led trip to view the eclipse from Glendo, Wyoming. Our 12-day tour takes you to Rocky Mountain National Park, where you'll tour the historic city of Cheyenne before experiencing totality. Then continue on to see breathtaking natural sights in Colorado and Utah, including Arches National Park, Canyonlands National Park, and the ancient Pueblo Indian site at Mesa Verde National Park. The 5-day option will end after the eclipse.
