Previously, scientists couldn't tell if nebulae (fuzzy clouds of light) were within the Milky Way or not. Hubble measured the distances to Cepheid stars in the Andromeda nebula and showed it was a hundred thousand times as far away as the nearest stars—proof it was a separate galaxy. He wrote a letter to Harlow Shapley on 19 Feb 1923 about his first measurement. New York Times (22 Nov 1924) told the public, before the meeting.«
