Our Solar Dynamics Observatory observes the Sun in ten different wavelengths, because each wavelength reveals different solar features. Here, we compare two images taken at nearly the same time but in different wavelengths of extreme ultraviolet light. The red image, which captures material not far above the Sun’s surface, is especially good for revealing details along the edge of the Sun, like the small prominence at the ten o’clock position. The bronze image clearly shows two large coronal hol

In its 10 years observing the Sun, our Solar Dynamics Observatory satellite has gathered over 425 million high-resolution images of our star. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 1
