a scientific institution in Washington, D.C., part of the Smithsonian Institution. The observatory was founded by S. Langley in 1890 specifically to make precise measurements of solar radiation, for which it was appropriately equipped. From 1907 to 1944 it made several tens of thousands of measurements of the solar constant under the direction of C. Abbot. After World War II its program was broadened considerably to include work mainly in theoretical astrophysics and satellite geodesy; a global network of satellite observation stations was organized for the latter research. The work is conducted in close cooperation with other American observatories. The observatory publishes Annals of the Astrophysical Observatory of the Smithsonian Institution (since 1900) and Smithsonian Contributions to Astrophysics (since 1956). [23–1830–]
