Hubble and Milton L. Humason formulate what is now known as Hubbles law by combining Cepheid distances to several galaxies with Vesto Sliphers measurements of the speed at which those galaxies recede from us
The redshift in light coming from distant galaxies is proportional to their distance, the law is first formulated by Edwin Hubble and Milton Humason after nearly a decade of observations. Discovers Hubbles Law
Hubble publishes the velocity distance relation showing that galaxies recede faster at greater distances
The redshift in light coming from distant galaxies is proportional to their distance, the law is first formulated by Edwin Hubble and Milton Humason after nearly a decade of observations
Humason provides redshift measurements used by Hubble to support the velocity distance relation
Sandage begins revising extragalactic distances and expansion measurements after Hubbles work
Baade's revised Cepheid calibration doubles the extragalactic distance scale and improves measurements used to estimate the expansion rate of the universe.
