Computing for radio astronomy, 1960s. Computer operators Sandy Braun (standing) and IBM employee Mary Jennings (seated) handling radio astronomy data in a computer room in Charlottesville, USA, in 1967. Every day, staff drove here with tapes of telescope data from the National Radio Astronomy Observatory (NRAO) at Green Bank, West Virginia, USA. Handwritten processing programs were transferred to cards using a keypunch. Braun is feeding the punch cards into the computer. It would return hundreds of pages of data that were checked by eye then sent back to Green Bank. Jennings is at the main terminal with a teletype keyboard with printer output (no display screen). The computer is an IBM 360 series, and the operating system was known as OS/360. The computer programs were probably written in PL/1 or Fortran.
