Compare Multispectral Sun Images
This interactive viewer allows you to compare images of the Sun side-by-side. The images were taken with light of different colors or wavelengths, including some from the infrared (IR) or ultraviolet (UV) regions of the electromagnetic spectrum, which our eyes cannot see.
- Choose a time from the first popup menu: the peak of the sunspot cycle (Solar Max), the low point in solar activity (Solar Min), or the most recent image.
- Pick a color or wavelength for the left-hand image.
- Select a different color for the right-hand image - and then compare the features you can see in the two images.
