The essential requirement is the ability to be able to carry out continuous observations of the galactic bulge. A telescope situated at Dome A or Dome C in Antarctica would be eminently suitable. Two possible observing strategies are described here. One employs a 1m visible (V and I passbands) telescope, the other a 2m wide-field near infrared telescope. Either telescope could allow a rough measurement of the abundance of Earth-like planets in the Milky Way to be made in a few years. Useful measurements could also be made on stellar atmospheres.9 pages, 2 figures, to appear in Acta Astronomica Sinica in Proc.
