CAPE TOWN, South Africa, Nov. 11 -- The Southern Hemisphere's largest single optical telescope -- powerful enough to detect objects as faint as a candle flame on the moon -- was officially inaugurated in a ceremony yesterday attended by approximately 1000 people, including South African President Thabo Mbeki. The Southern African Large Telescope (SALT) took five years to build at a cost of $20 million.
