Canis Major Dwarf

The Canis Major dwarf, identified in 2003 through the Sloan Digital Sky Survey, is a distinct concentration of stars situated near the Canis Major constellation within the Milky Way. Its origin remains a subject of investigation, with hypotheses proposing it as the consequences of a currently disrupting dwarf galaxy or a globular cluster influenced by the tidal forces of our galaxy. Populated by older, metal-poor stars, the region exhibits characteristics typical of ancient stellar populations. The Canis Major dwarf is associated with a stellar stream, hinting at a possible connection to a galactic interaction or disruption. As part of the extended halo structure of the Milky Way, the study of this dwarf contributes valuable insights into the formation and evolution of our galaxy, shedding light on the intricate processes governing the hierarchical assembly of celestial structures.
