Other Galaxy Classifications

  • Exhibition Text

    • The classification of galaxies by shape relies upon images made with visible light. But galaxies observed in other wavelengths, or with longer exposure times, or at earlier cosmic epochs, show the need for additional categories. Many such categories exist. They may indicate different ways that galaxies form, or may show various stages through which galaxies evolve.
