For the last three years, NASA's Solar Dynamics Observatory (SDO) has been tracking our sun - the one and only - as it approaches "solar maximum."
That's the scientific term for the star's peak in solar activity each 11 years, and in this new video, NASA has condensed that time span into three minutes.
You can see eclipses, sunspots, solar flares and more. Fluctuations in size are due to changes in distance between it and the spacecraft taking the pics.
