Most experts advise against staring at the sun for more than a few seconds, and yet, a new timelapse from NASA lets viewers peer into the fiery mass for an entire decade. During the course of ten years, the Solar Dynamics Observatory took more than 425 million images of the massive star that were captured .75 seconds apart. Aggregated into an hour-long compilation titled “A Decade of Sun,” the photographs provide visual evidence of how the giant orb functions and its influence on the rest of the solar system. Each image was captured at a wavelength of 17.1 nanometers, or one-billionth of a meter, to show the exterior atmospheric layer that’s called the corona.
NASA has shared on YouTube a list of notable moments, including an appearance by Venus and an iconic interruption in 2012. Most of the dark spots in the video are a result of the earth or moon passing in between the Solar Dynamics Observatory and blocking its view, although there was a longer lapse in 2016 due to an equipment malfunction. When the spacecraft was recalibrating its tools, the sun shifts to one side of the screen.
