Big Science refers to the style of scientific research developed during and after World War II that defined the organization and character of much research in physics and astronomy and later in the biological sciences.
Big Science is characterized by large-scale instruments and facilities, supported by funding from government or international agencies, in which research is conducted by teams or groups of scientists and technicians. Some of the best-known Big Science projects include the high-energy physics facility CERN, the Hubble Space Telescope, and the Apollo program.
In Europe alone there are more than 100 international and national research facilities. The web site MERIL (Mapping of the European Research Infrastructure Landscape) gives a good overview of these many research facilities.
