NASA | SDO: Three Years of Sun in Three Minutes

This three years of sun in three minutes courtesty of  NASA's Solar Dynamics Observatory (SDO) is mesmerizing and fascinating, especially when watched in 1080 HD/Full screen.

During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time. The image is, however, remarkably consistent and stable despite the fact that SDO orbits the Earth at 6,876 miles per hour and the Earth orbits the sun at 67,062 miles per hour.
