The Video captures solar activity from August 12 to December 22, 2022, observed by NASA's Solar Dynamics Observatory (SDO). Orbiting Earth, SDO has provided 4K x 4K images of the Sun for 13 years, revealing insights into its behavior and impact on the solar system. Equipped with three instruments, SDO records Sun images every 0.75 seconds. Notably, the Atmospheric Imaging Assembly (AIA) captures shots every 12 seconds at 10 wavelengths, including extreme-ultraviolet light at 17.1 nanometers, revealing the corona. The resulting 133-day timelapse, comprised of images taken 108 seconds apart, condenses observations into a 59-minute video. The Sun's rotation (about 27 days per rotation) is evident, displaying bright regions, magnetic loops, and solar flares. Occasional dark frames are due to eclipses by Earth or the Moon, instrument downtime, or data errors. SDO transmits 1.4 terabytes of data daily. Offset Sun images arise during instrument calibration. Future NASA missions will continue solar study, informing space insights and safety.
