Explore the Suns features and see current solar images courtesy of NASAs Solar Dynamics Observatory. You can also get a preview of what youll 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 youre 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 Suns corona. This also has a challenge mode where youre asked to not only find various features, but identify the point in an eclipse when they appear.
Todays Sun: interactively explore and compare real time images from NASAs Solar Dynamics Observatory in several different wavelengths.
