Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.

During the Smithsonian s inaugural Educator s Day program, teachers learned about classroom-ready tools, transferable teaching approaches, and opportunities for ongoing professional learning.
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.
