HST Key Project (original) (raw)

The Hubble Space Telescope Key Project on the Extragalactic Distance Scale

"The distance scale path has been a long and tortuous one, but with the imminent launch of HST there seems good reason to believe that the end is finally in sight."

Marc Aaronson (1985 Pierce Prize Lecture)

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.
