The $85 million Very Large Baseline Array (VLBA) will allow radio astronomers
to observe details in astronomical objects more than 1000 times finer than
any that can be seen by optical telescopes, for example the jets fo material
coming from the cores of quasars, where giant black holes are believed to
lurk. The 10 25-metre radio dishes of the VLBA are scattered across North
America with outlying stations in Hawaii and the Virgin Islands.
