NASA's Solar Dynamics Observatory<https://sdo.gsfc.nasa.gov/> has been consistently taking pictures of the sun -- one every three-quarters of a second -- across a number of different wavelengths. Images of the extreme ultraviolet wavelength of 17.1 nanometers reveals the sun's corona, and hourly corona pictures have been combined into a time-lapse movie of the last decade of solar activity, condensed into about 60 minutes<https://www.nasa.gov/feature/goddard/2020/watch-a-10-year-time-lapse-of-sun-from-nasa-s-sdo>.
