Cepheids are the pillar of the extragalactic distance scale, but their reach in distance is not sufficient to calibrate H0 Yet HST has provided Cepheid distances to eight galaxies which have produced SNe la. The latter are used as nearly perfect standard candles to carry the distance scale to 30 000 km s−1, giving H0 = 58 ± 5. This determination finds support in other methods, but its range in distance and its weight is unparalleled.
