At the turn of this century, astronomers were confident they understood the Milky Way’s relationship with its galactic neighbors. Our home galaxy is the second-largest member of the Local Group, an assembly of more than 50 galaxies that spans roughly 10 million light-years. Many of the group’s smaller galaxies are satellites of the Milky Way—two of the closest companions are the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). Streams of gas and dust ripped from these dwarf…
