For years, astronomers have grappled with the “missing satellites problem” in our Milky Way galaxy. The standard dark matter model predicts more satellite galaxies than we’ve observed, leaving scientists puzzled. But recent observations from the Subaru Telescope shed light on this cosmic mystery.
The Subaru Telescope, perched atop a Hawaiian mountain, teamed up with the Hyper Suprime-Cam (HSC) to scan the skies. Their mission: find elusive dwarf galaxies that might be lurking far from our galactic neighbourhood. And they succeeded.
To settle the score, astronomers need more high-resolution imaging and analysis. Enter the Vera C. Rubin Observatory in Chile, set to scan the skies next year. With its broader view, scientists hope to uncover even more satellite galaxies and unravel the secrets of dark matter.
