THE space agency Nasa has created a time-lapse video of images of the sun taken over the past three years.
The agency Solar Dynamics Observatory has been orbiting our planet since 2010, keeping a watchful eye on our sun.
During that time, we've seen amazing things: massive, absolutely massive, solar flares, the planet Venus transiting the solar face, and a mystifyingly beautiful phenomenon known as solar rain.
The video above compresses those three years into four minutes, using two frames from each Earth day.
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.
