The image is a black background with numerous white circles representing stars. Each star is labeled with a number from 1 to 23. The stars are scattered across the image, with varying distances between them. A faint, curved line connects stars 1, 5, 13, and 20, possibly indicating a constellation or a specific grouping. The numbers are positioned near each star, providing identification. The text at the bottom reads "STARS WHOSE DISTANCES ARE BEST KNOWN. (See Table.)", suggesting this is a diagram related to astronomical measurements.
