The Hubble Space Telescope Key Project on the Extragalactic Distance Scale
The main goal of the HST Key Project on the Extragalactic Distance Scale is to determine the Hubble Constant, H0, to an accuracy of +/- 10%. This goal will be achieved by the systematic observations of Cepheid variable stars several galaxies using the Hubble Space Telescope. The Key Project team currently has 28 members. A list of Key Project papers that have been published, in press, submitted, or in preparation is available.
Archives of the Extragalactic Distance Scale Key Project. Archival material appears after the paper has been accepted for publication. Preprints for papers in press can be found in the publication list or in the archives.

Edwin Hubble
During the past 100 years, astronomers have discovered quasars, pulsars, black holes and planets orbiting distant suns. But all these pale next to the discoveries Edwin Hubble made in a few remarkable years in the 1920s. At the time, most of his colleagues believed the Milky Way galaxy, a swirling collection of stars a few hundred thousand light-years across, made up the entire cosmos. But peering deep into space from the chilly summit of Mount Wilson, in Southern California, Hubble realized that the Milky Way is just one of millions of galaxies that dot an incomparably larger setting.
