The free Totality app was created by Big Kid Science, which subsequently donated the app to the American Astronomical Society (AAS).
For additional eclipse information beyond what you find within the Totality app, please visit the American Astronomical Society (AAS) Eclipse Pages (eclipse.aas.org).
There are many other great resources available to help you learn more about eclipses. Here are a few of our favorites.
General Eclipse Resources
- For an overview of the eclipse experience, including info about what to do if you have clouds on eclipse day, start with this page from the American Astronomical Society; use the menu at the top of the page to find other great eclipse resources from the American Astronomical Society.
- Xavier Jubier’s Interactive Maps provide the underlying code for the maps in the Totality app, and the same code powers his web-based versions.
- Weather prospects for upcoming eclipses (especially important if you are planning an eclipse trip): Jay Anderson’s Eclipsophile.com.
- TimeandDate.com has tons of information not only about eclipses (both solar and lunar) but about the night sky more generally.
- Fred Espanek’s “Mr. Eclipse”: Fred sadly passed away in 2025, but his site is still a fantastic resource about eclipses throughout history.
- Michael Zeiler’s Great American Eclipse: Though focused on the 2017 and 2024 USA eclipses, it also has lots of other info about eclipses past and future.
- Hermit Eclipse offers a compilation of data from other sites that is organized very nicely, especially if you are looking for details on how to view upcoming eclipses.
- Jamie Carter’s When is the Next Eclipse? provides information on eclipses throughout the 21st century.
- Dan McGlaun’s “eclipse simulator” allows you to view simulations of upcoming eclipses as they will appear from different locations and his eclipse prediction page discusses the mathematics of eclipse prediction.
- Doug Duncan’s Coursera Course About Eclipses
Eclipse Travel
Interested in traveling to see totality? It’s a great idea, especially if the eclipse is happening in a place that you’ve always wanted to go to anyway. You can plan your own trip with the help of the Totality app, or book with an experienced eclipse tour operator who can ensure you are in the right place for totality at the right time. You can find many great eclipse tours online, including the following for which app creator Dr. Jeff Bennett will be a speaker:
- For the 2027 eclipse (August 2): Doug Duncan’s Gibraltar eclipse experience.
Eclipse Watching Events
It can be fun to watch an eclipse with a group, and many communities will be hosting eclipse watching events for upcoming eclipses. These will often include astronomers helping you understand what you are seeing, opportunities to view the Sun through telescopes equipped with solar filters, and much more. Search for events in the area where you plan to be.
