History
Sky & Telescope was founded in 1941 by Charles A. Federer Jr. and Helen Spence Federer. From its inception, the magazine aimed to serve the amateur astronomy community while also covering professional astronomical research. Over the decades, it built a reputation as one of the most authoritative and widely read astronomy publications in the world. Its editors have included many distinguished amateur and professional astronomers, several of whom have had asteroids named in their honor. The magazine expanded its reach through a comprehensive website, digital editions, and podcasts. On July 3, 2019, the American Astronomical Society (AAS) purchased the Sky & Telescope line of businesses, ensuring the magazine's continuation under a non-profit scientific society. The AAS, founded in 1899, is the major organization of professional astronomers in North America. Under AAS ownership, Sky & Telescope continues to publish from Cambridge, Massachusetts, and remains a vital resource for astronomy enthusiasts globally.
