The Smithsonian Astrophysical Observatory (SAO) was established in 1890 as research unit of the Smithsonian Institution concentrating on studies of solar radiance. Sixty-five years later, SAO assumed responsibility for establishing an optical network for tracking the first artificial satellites. From this pioneering effort, the size and scope of SAO grew with the international space program to include major research in virtually all branches of astrophysics, as well as in areas of earth and planetary sciences.
Since 1955, when its headquarters moved to Cambridge, Massachusetts, SAO has pursued such research in close collaboration with the Harvard College Observatory (HCO) and Harvard University Department of Astronomy. On July 1, 1973, the Smithsonian Institution and Harvard University formalized their collaboration now known as the Center for Astrophysics | Harvard & Smithsonian (CfA) to coordinate the related research activities of the two observatories under a single director.

The City of Tucson and Pima County are beginning the process of updating their Outdoor Lighting Code for the first time in almost a decade, and dark sky advocates say the proposed changes have been a long time coming.
The lighting ordinance, which regulates lighting quality and light emissions standards throughout Pima County, was last comprehensively revised in 2012.
âTypically, these codes are updated every three to six years,â said Daniel Ice, Pima Countyâs Chief Building Official. âSo we are past due for an update.â
A newly discovered exoplanet named TOI-1685 b is exceptionally fast moving as astronomers calculated that it zips around its host star every 0.67 Earth days. TOI-1685 b is located approximately 122 light-years away from Earth and it orbits so close to a red dwarf star (also known as M dwarf) that it has an estimated surface temperature of 1,465 degrees Fahrenheit (796 degrees Celsius).
The team of researchers, led by Paz Bluhm from Heidelberg University in Germany, discovered the exoplanet through data gathered by NASA’s Transiting Exoplanet Survey Satellite (TESS) and confirmed it by data collected by the CARMENES spectrograph instrument on the 3.5-meter telescope at Spain’s Calar Alto Observatory.
While the existence of the candidate planet is yet to be confirmed, the lead author of the new study reportedly announced that there could be other planets throughout.
