NASA’s Eyes

Welcome to Eyes on the 2017 Eclipse! In this interactive, 3D simulation of the total eclipse of August 21st, 2017, you can see a view of the eclipse from anywhere on the planet.

Once you have downloaded and installed the program, click on the “Launch” button. Once it has loaded, click on the “Explore” button at the bottom of the screen, and a split-screen view will appear showing a view of the Earth on the left side, and a view of the sun from your selected location on the right side. Try rotating and zooming into the globe. Then, select a location either by clicking directly on the Earth, by selecting one of the five preset locations, or by clicking the “Custom” button and entering the latitude and longitude in decimal degrees (For example, Los Angeles is located at 34.05 North, 118.25 West).

Once you have chosen a location, you can then watch a simulation of what the eclipse would look like from that area from start to finish!

Was your selection only a partial eclipse? Pick a location in the narrow center line of the shadow path, or “umbra,” to see a total eclipse. Then plan to travel to that spot on the day to have a once-in-a-lifetime experience.

***NEVER look at the sun directly without proper solar glasses or filters — you can severely damage your eyes.***
