# Edwin Hubble (@edwin-hubble)

Edwin Hubble was an American astronomer whose observations helped establish that the Milky Way is one galaxy among many and that more distant galaxies generally recede faster. His work helped turn cosmology into an observational science.

These achievements were cumulative. Hubble relied on Henrietta Leavitt’s distance relation, Vesto Slipher’s redshift measurements, Milton Humason’s observations, and theoretical work by Georges Lemaître, whose contribution is now recognized in the name Hubble–Lemaître law.
