Before the Launch of Hst, estites of the Hubble constant typically had errọrs of up to 50%, but Hubble measurements of cepheid variables in the Virgo Cluster and other distant galaxy Clusters provided a measured value with an Accuracy of +10–10, which is consistent with other more accurate measurements made since Hubble's Launch using other Techniques.While Hubble helped to re estites of the age of the Universe, it also cast Igun Igun the ori about its future..
