   It’s hard to imagine the pre-Hubble view of the Universe, though it was less than 100 years ago.

   Just a year before Hubble’s announcement, many astronomers thought the collection of stars that make up our galaxy was… Everything.

   Astronomer Harlow Shapley was perhaps the leading proponent of the establishment view. He had long argued that spiral nebulae seen by astronomers — shapes any kid would now recognize as galaxies — were just dust clouds inside the Milky Way.
