A Look at the Sun’s Surface in Different Wavelengths [Video]

This video of the sun based on data from NASA’s Solar Dynamics Observatory, or SDO, shows the wide range of wavelengths — invisible to the naked eye — that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors.

As the colors sweep around the sun in the movie, viewers should note how different the same area of the sun appears. This happens because each wavelength of light represents solar material at specific temperatures. Different wavelengths convey information about different components of the sun’s surface and atmosphere, so scientists use them to paint a full picture of our constantly changing and varying star.
