1991Aperture Synthesis Telescopes — Commissioning tests and observations have been made using three antennas in the Australia Telescope (AT), spaced up to 2km apart, and the first image of a radio source observed at 6cm was produced in 1989. The IRAM millimeter array in France comprizing three 15-m antennas has been commissioned at 3mm. A fourth antenna is

Physics Today, 1950
Until recently astronomy was restricted to the visual band of the electromagnetic spectrum, and to wavelengths near to the visual band. Our immense store of astronomical knowledge has been obtained from observations made in a band of about four octaves of the spectrum, although measuring techniques are available for about forty octaves.
