Large Scale Structure Emerges

As the number of galaxies mapped in three dimensions grew from hundreds to thousands to tens of thousands large scale structures began to emerge.  It appeared that galaxies were not distributed uniformly throughout space.  Rather there were huge voids, like vast bubbles where there were no galaxies at all, and long filiaments and sheets filled with galaxies.  The largest structure of all, known as the “Great Wall” of galaxies was discovered and reported in 1989, which is when Geller’s and Huchra’s project came to the attention of the media.
