Edwin Hubble, Albert Einstein, and fellow scientists at the Hale Library, 1931 This framed historical photograph is on display at Carnegie Science’s Hale Library in Pasadena, California. It shows a group of scientists who gathered at Mount Wilson Observatory’s Hale Library, Santa Barbara Street offices, Pasadena, California. Standing, left to right, are Milton L. Humason, Edwin Powell Hubble, Charles St. John, Albert Abraham Michelson, Albert Einstein, William Wallace Campbell, and Walter S. Adams. The photo was taken during Einstein’s visit in early 1931, eight years after Hubble’s discovery that the Andromeda Nebula was a separate galaxy. The same library hosted the Oct. 13, 2026, ceremony celebrating the resolution supporting National Beyond the Milky Way Day. Sarah Al-Ahmed / The Planetary Society.
