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.
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.
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.
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.
