Welcome to the Caltech Archives

 

The Caltech Archives
was formally established in 1968 to serve as the collective memory of the California Institute of Technology. Our mission is to preserve and make accessible the institutional records, personal papers, documents, artifacts and pictorial materials that tell the school's history.

The Archives' unique research collections in the history of science and technology range from the time of Copernicus to today. They are available to the campus community for instructional and research purposes, as well as to qualified non-campus users by appointment.

50 Years of the Owens Valley
130-Foot Radio Telescope

Lifting 130-foot radio telescope dish onto pedestal

This year marks two important anniversaries for the Owens Valley Radio Observatory (OVRO), one of the largest university-operated radio telescope facilities in the world. Managed by the Caltech Astronomy department and located on the East side of the Sierra Nevada, OVRO was inaugurated in 1958 and continues observations to this day.

Its iconic 130-foot radio antenna was dedicated on October 18, 1968, and it soon made its mark in the single-dish spectroscopy of interstellar clouds and in very long baseline interferometry (VLBI), paired with antennas thousands of kilometers away. Here is a selection of photos from our OVRO collections, chronicling the construction of the 130-foot radio telescope. EP - Posted 10-18-2018
