Dark matter ‘nuggets’ could explain the Milky Way’s mysterious glow

Scientists propose that mysterious ultraviolet light detected across the Milky Way could originate from dark matter "nuggets" made of axion particles colliding with ordinary matter. These theoretical axion quark nuggets are incredibly dense clumps that exist in both matter and antimatter forms, with antimatter versions annihilating upon contact with regular matter to produce the observed far-ultraviolet glow. Computer simulations matching the nugget theory to spacecraft observations show promising results, potentially solving a decade-old astronomical puzzle while advancing understanding of dark matter's nature.
