Whose observations first revealed the expansion of the universe?
SpaceCosmology
Quick Answer
Edwin Hubble’s observations in the 1920s showed that galaxies are moving away from us, implying that the universe is expanding. This became a landmark result in cosmology.
The Full Story
Edwin Hubble used observations from the Mount Wilson Observatory in the 1920s to study galaxies beyond the Milky Way. By measuring their redshifts, he showed that distant galaxies are receding from us, with faster recession at greater distances. This relationship became known as Hubble’s law. Although other scientists contributed to the theoretical framework, Hubble’s data made the expanding universe widely accepted. His work transformed astronomy and cosmology in the 20th century.
