SUMMARY:The Virgo Cluster of Galaxies\, WHITFORD LECTURE \, Laura Farr
 arese\, Herzberg Institute of Astrophysics\, Univ of British Columbia
DESCRIPTION:At a distance of 16.5 Mpc and with a gravitating mass of 4
 .2A--10^14 solar masses\, the Virgo Cluster is the dominant mass conce
 ntration in the local universe\, the centre of the Local Supercluster\
 , and the largest concentration of galaxies within ~35 Mpc. With thous
 ands of member galaxies lying at a nearly common distance and spanning
  virtually all known morphological types\, it has historically played 
 a key role in studies of how galaxies form and evolve in dense environ
 ments. It is\, without question\, the most thoroughly studied cluster 
 of galaxies in the universe\, and remains a preferred target for a sys
 tematic survey of baryonic substructures in the low-redshift universe.

\nIn this talk\, I will describe an ambitious optical imag
 ing survey of the Virgo cluster\, the Next Generation Virgo Cluster Su
 rvey (NGVS)\, that is being carried out using the MegaPrime instrument
  at the Canada France Hawaii Telescope (CFHT). The NGVS is designed to
  address a wide range of fundamental astrophysical questions\, includi
 ng: the faint-end shape of the luminosity function\, the characterizat
 ion of galaxy scaling relations over a factor 10^7 in mass\, the clust
 er/intracluster medium/galaxy connection\, and the fossil record of st
 ar formation and chemical enrichment in dense environments. I will pre
 sent a brief overview of the NGVS and discuss preliminary results.<br>
