This image has three panels: one on the right, taking up about half the image, and two stacked on the left. In the upper left is a Hubble image of Betelgeuse. The star looks like a glowing ball of yellow light with a bright yellow circle in the center that fades outward to a dark orange. The outer edges appear hazy. Below the image of Betelgeuse are three scale bars. The first shows the size of the star as seen in the Hubble image above. Below that is a scale bar showing the size of Earth’s orbit, which is about a 15% the length of the star’s size. Finally, the last scale bar shows the orbit of Jupiter, which is about 70% as long as the star’s size. The panel on the right shows a black background with many stars of different sizes dotted around the image. The stars of Orion are called out with light white lines drawn between the major stars. An arrow points to one star at the upper left, the location of Betelgeuse.
