Sagittarius Dwarf

The Sagittarius Dwarf Galaxy, discovered in 1994 through the Two Micron All Sky Survey, stands as a diminutive and irregularly shaped satellite galaxy of the Milky Way. Characterized by its dwarf spheroidal structure, the Sagittarius Dwarf is currently engaged in a dynamic gravitational interplay with the Milky Way, leading to its tidal disruption. This ongoing interaction manifests in the creation of extensive tidal tails, comprised of stars that have been stripped away from the Sagittarius Dwarf and now encircle the Milky Way. These tidal tails serve as invaluable cosmic fingerprints, offering insights into the composition, dynamics, and evolution of both the Sagittarius Dwarf Galaxy and the Milky Way. The gravitational influence of the Sagittarius Dwarf on the Milky Way contributes to our understanding of galactic accretion and merging processes, enriching our comprehension of the broader cosmic narrative.
