$Three panels, each showing a different view of the binary star system Alpha Centauri. The panel at the left is a Digitized Sky Survey image showing a single bright point source at the center of a black image with small stars scattered throughout. The very center of this bright source is outlined with a vertical box, tilted slightly to the left, with two diagonal lines leading to the second panel. The Hubble Space Telescope image shows two white stars with 4 diffraction spikes each against a black background. The top star is labeled Alpha Cen B and the bottom Alpha Cen A. Alpha Cen A is outlined with a white square with two diagonal lines leading to the third panel at the furthest right, which shows a James Webb Space Telescope image of the star. Within a large white circle there is a blurry red-toned field with an orange star icon and central black circle outlined in white marking the location of Alpha Cen A. A bright orange blob at 9 o’clock in relation to the star is labeled “S1” and circled.$
