Guaranteed Goosebumps! New Galaxies Discovered SPACE MYSTERIES Makes the Milky Way Galaxy Look Puny!

Today, we know that galaxies are the basic building block of the universe: island cities of stars. A century ago Edwin Hubble first discovered that galaxies were actually other so-called "island universes," distributed far beyond our Milky Way in all directions.

Edwin Hubble cataloged galaxy shapes: spiral, elliptical, and irregular, and pondered if there was an evolutionary link. Did galaxies morph from one shape into another over time? He also described them as the "markers of space," because their apparent recession velocities were evidence the universe was expanding in all directions.
