The video features a computer-generated image of a galaxy. The galaxy is predominantly purple and white, with a bright white center that appears to be the nucleus. The galaxy is rotating, as indicated by the text "Rotation" and "Actual Rotation (observable mass + dark matter)" on the screen. The text "CLICK TO WATCH" is prominently displayed at the bottom of the screen. The video also includes a scale indicating the distance from the viewer to the galaxy.
