The National Eclipse Blog contains posts on eclipse-related topics of interest. Because major eclipses only occur every couple of years, we don't post here often, but you'll usually notice a flurry of activity in the lead-up to big eclipse events. In the meantime, enjoy our posts from past eclipses.

Clouds | May 8, 2024

It's already been a month since the long-awaited and much-anticipated 2024 total solar eclipse swept across North America. And what a wild eclipse it was!

How to Prevent Clouds and Bad Weather from Spoiling a Successful Eclipse Viewing on April 8

Clouds | Feb 16, 2024

A total solar eclipse is a very precise phenomenon. For hundreds of years into the future, astronomers can predict exactly what time an eclipse will occur, down to the tenth of a second, and exactly where the Moon's shadow will touch the surface of the Earth, down to the foot.

What is an Annular Eclipse?

Annular Solar Eclipse | Sep 14, 2023

We're now less than one month away from the next solar eclipse in America. On October 14, 2023, an annular, or "ring of fire," solar eclipse will cross over eight U.S. states.

Crossing Paths: A Look at Every 21st Century Total Solar Eclipse Path Crossing in the U.S.

21st Century Total Solar Eclipse Path Crossings | Jan 14, 2021

Back in 2016, we posted a short article about how the path of the 2017 total solar eclipse would be crossed by the path of the 2024 total solar eclipse, creating a zone of overlapping totality spanning parts of Missouri, Illinois, and Kentucky.

Living in the Future

1918/2017 Total Solar Eclipse Map | May 10, 2017

If someone asked you to picture the world in the year 2116, 99 years from now, what would you see? Would you see flying cars and colonies on Mars? The future usually doesn't turn out quite the way we imagine it might. And the world of today probably looks nothing like the Americans of 1918 pictured... Read more

Debunking the 2017 Eclipse

Debunked | Apr 4, 2017

In our last post, "Staying Safe on August 21," we called attention to the fact that the media sometimes inadvertently provides incorrect or dangerous information about how to safely view a solar eclipse. Needless to say, this is a disturbing pattern because so many people never think to verify or fa... Read more

Staying Safe on August 21

Eclipse Glasses | Mar 13, 2017

The most important thing to consider when planning for a solar eclipse isn't your location within the path of totality, your distance to the centerline, or even the weather. It's eye safety.

2017/2024 Total Solar Eclipse Map | Jun 28, 2016

It's been said that, on average, a total solar eclipse can be seen from the same place only once every 375 years.

Why a Solar Eclipse Can Never Occur on Easter

Full Moon | Mar 25, 2016

This year—2016—Easter Sunday falls on March 27, one of those years when it feels like the holiday arrives too early. In 2008, we had the earliest Easter in almost a century when it occurred on March 23, its earliest arrival since 1913. Next year, we'll celebrate Easter much later, on April 16. We ce... Read more
