Astronomical advances often depend upon technological advances. In recent years charge‐coupled‐device detectors on existing telescopes have reached photon efficiencies approaching 100%, significantly better than those of photographic detectors. (See PHYSICS TODAY, March, page 19.) “The 5‐meter Hale telescope with a charge‐coupled‐device detector is equivalent to a 50‐meter diameter telescope equipped with 1948 photographic plates,” says Peter Waddell (University of Strathclyde, Glasgow), who is… Expand
