Summary
The sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun's atmosphere, the corona. SDO's sixth year in orbit was no exception. This video shows that entire sixth year--from Jan. 1, 2015 to Jan. 28, 2016 as one time-lapse sequence. At full quality, this video is ultra-high definition 3840x2160 and 59.94 frames per second. Each frame represents 1 hour. SDO's Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths. The images shown here are based on a wavelength of 171 angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin (about 1 million degrees F.) In this wavelength it is easy to see the sun's 25-day rotation. During the course of the video, the sun subtly increases and decreases in apparent
