Quick Answer
One of the earliest major galaxy redshift surveys was published in 1977. It helped map the large-scale structure of the universe.
The Full Story
A landmark early galaxy redshift survey was published in 1977, building on work by astronomers such as Margaret Geller and John Huchra in the late 1970s and early 1980s. By measuring galaxy redshifts, astronomers could estimate how far away galaxies are and map their three-dimensional distribution. These surveys revealed that galaxies are arranged in clusters, filaments, and vast voids rather than being spread uniformly. They became fundamental to modern cosmology.
