A recent study has revealed that medieval observations of the moon are proving helpful for the researchers investigating the enigmatic astronomical objects known as ultracompact dwarfs. These objects are similar to globular clusters, but are so dense that they contain a significant number of stars. To study the locations of these objects, researchers went back to the Middle Ages and examined the observations of the moon to refine their understanding of its position in the sky. The study provides new insight into the positioning of ultracompact dwarfs in the Milky Way galaxy and may inform future research on these objects.
