Number 42 (Story #2), July 24, 1991 by Phillip F. Schewe and Ben Stein INDIVIDUAL STARS IN THE GALAXY NGC4571 HAVE BEEN RESOLVED with the Canada-Hawaii-France Telescope on Mauna Kea. These are the most distant single stars ever seen. Astronomers Robert McClure (604-388-0021) and Michael Pierce of the Dominion Astrophysical Observatory in Victoria, Canada use the apparent spacing of the stars and their brightness to calculate a value for the distance between Earth and the Virgo cluster (in which NGC4571 resides) of 50 million light years, which in turn implies a Hubble constant of about 85. This value, rather high as Hubble constant estimates go, further complicates the general effort to establish a consistent cosmic yardstick. Astronomers hope that a rejuvenated Hubble Space Telescope, with its keen resolution brought into play through corrective optics, may elucidate the matter by looking at single stars in many galaxies.
