Summary

Description
English: This is the 100 inch (2.5 M.) Hooker Telescope at the Mount Wilson Observatory in Los Angeles County, California. It was used by Edwin Hubble to determine that some nebulae were actually galaxies outside our own Milky Way. Hubble, assisted by Milton L. Humason, discovered the presence of the redshift that indicated the universe is expanding.
