The research, led by scientists from Japan, Taiwan and the United States, used the powerful Subaru Telescope in Hawaii, known for its ability to detect faint dwarf galaxies. The latest discovery of Virgo III and Sextans II brings the total number of discovered satellite galaxies to nine. True, this is still much less than the 220 satellite galaxies predicted by traditional dark matter theory.
But the study points to a possible “too many satellites problem” and suggests that there could be as many as 500 satellite galaxies around the Milky Way, according to astronomers’ new models.
Future observations with modern telescopes, such as the Vera C. Rubin Observatory in Chile, will allow for more in-depth study and mapping of these satellite galaxies.
