The video starts with a black screen and then transitions to a graphical representation of the sun. The sun is shown in a yellow and orange color, with a black circle in the center representing the sun's core. The sun is surrounded by a grid and a timeline at the bottom of the screen. As the video progresses, the black circle in the center of the sun expands and contracts, indicating the sun's pulsating activity. The video also includes a graph at the bottom of the screen that shows the sun's magnetic field activity over time. The graph has a purple line that fluctuates, representing the strength of the magnetic field. The video ends with the black circle in the center of the sun expanding and contracting rapidly.
