Explore the Sun’s features and see current solar images courtesy of NASA’s Solar Dynamics Observatory. You can also get a preview of what you’ll see in a total solar eclipse.

This educational app about our Sun has three pieces:
• Filters: explore the Sun in different wavelengths. This includes a challenge mode where you’re asked to find various features on the Sun (sunspots, active regions, magnetic field structures, etc.)

• Eclipse: make your own eclipse by dragging the moon in front of the Sun, and discover eclipse features like the “diamond ring” and the Sun’s corona. This also has a challenge mode where you’re asked to not only find various features, but identify the point in an eclipse when they appear.

• Today’s Sun: interactively explore and compare real time images from NASA’s Solar Dynamics Observatory in several different wavelengths.
