If you missed Monday's solar eclipse or regret that you didn't travel to a spot in the path of totality, you can start planning for next time.

Images show the Great American Eclipse, seen by tens of millions of people in parts of Mexico, 15 U.S. states and eastern Canada for the first time since 2017.

A total solar eclipse was visible over parts of Mexico, 15 U.S. states and eastern Canada on Monday. The rest of the continental U.S. got to see a partial eclipse.

Here's where and when to see the rare celestial event, how to view it safely and a few fun milestones to look out for if you're lucky enough to be in the path of totality.

Monday’s total solar eclipse will be visible along a “path of totality” that measures more than 100 miles wide and crosses 15 U.S. states.

The launch on a SpaceX Falcon 9 rocket from the John F. Kennedy Space Center in Florida comes as both Koreas are pursuing military capabilities in space.

The differing gravitational force on the moon, and potentially other factors, change how time unfolds relative to how it is perceived on Earth.

For astrophysicists, the eclipse is a rare opportunity to study the sun — particularly its outer atmosphere, or the corona, which normally can’t be seen.

From finding safe glasses to building a pinhole projector, here’s what to know before the eclipse next month.

The image offers a never-before-seen view of the black hole at the center of our galaxy, as well as a clue that many or all black holes may share a pattern.

The eclipse could be a scientific bonanza, thanks to new spacecraft and telescopes, the moon's proximity to Earth and a chance of dramatic bursts of plasma from an active sun.
