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).
Beyond the American Astronomical Society (AAS) Eclipse Pages, 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.
- View simulations of upcoming eclipses as they will appear in many different locations using Dan McGlaun’s “eclipse simulator” (you’ll also find other great resources on this site, including the next resource below).
- Learn about the mathematics of eclipse prediction with Dan McGlaun’s eclipse prediction page, which is written in simple and accessible language.
- Michael Zeiler’s Great American Eclipse site — lots of info about eclipses past and future.
- The site 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” site — perhaps the ultimate source for information about eclipses of all types throughout history
- The Hermit Eclipse site, which is a compilation of data from other sites but organized very nicely, especially if you are looking for details on how to view upcoming eclipses.
- Jay Anderson’s Eclipsophile web site provides weather prospects for upcoming eclipses and more.
- Jamie Carter’s site When is the Next Eclipse? provides information on eclipses throughout the 21st century.
- Doug Duncan’s Coursera Course About Eclipses
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. 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.
