NASA's  <https://sdo.gsfc.nasa.gov/> Solar Dynamics Observatory 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

condensed into about 60 minutes.
