Abstract
Accurate distances to galaxies are critical for determining the present expansion rate of the Universe or Hubble constant (H_0). An important step in resolving the current uncertainty in H_0 is the measurement of the distance to the Virgo cluster of galaxies. New observations using the Hubble Space Telescope yield a distance of 17.1 ± 1.8 Mpc to the Virgo cluster galaxy M100. This distance leads to a value of H_0 = 80 ± 17 km s^(−1) Mpc^(−1). A comparable value of H_0 is also derived from the Coma cluster using independent estimates of its distance ratio relative to the Virgo cluster.
