"Unveiling Dark Matter's Trail of Stellar Clues in the Milky Way"

The Vera C. Rubin observatory in Chile plans to study gaps between streams of stars orbiting the Milky Way to gather clues about the nature of dark matter, an invisible substance surrounding galaxies. These stellar streams, resembling "strings of pearls," can reveal the influence of dark matter through disruptions in their starry trails. The observatory's unprecedented digital camera is expected to spot starry trails five times farther away than current telescopes, potentially unveiling new populations of stellar streams in the galaxy's outskirts. Additionally, NASA's upcoming Roman Space Telescope could help study stellar streams beyond the Milky Way, providing further insights into dark matter.
