According to their press release,

“Sky & Telescope chronicled astronomy’s progress and milestones every step along the way. Over the decades, it has become something of a “journal of record” for both professional and amateur astronomy, and especially the interface between them. Its thousands of authors over the years include such astronomical luminaries as James Van Allen, Cecelia Payne-Gaposchkin, Fred Whipple, Frank Drake, Gerard Kuiper, Carl Sagan, Sara Seager, and Phil Plait. Its award-winning editorial staff carries on the traditions of authoritative content and journalistic excellence set by founders Charles and Helen Federer.

From the construction of the 200-inch telescope on Palomar Mountain and the construction of the world’s first dedicated radio telescope in amateur’s yard — through the birth of the Space Age, interplanetary exploration, and Hubble (starting when it was just a gleam in Lyman Spitzer’s eye) — through today’s era of precision cosmology, exoplanets, gravitational waves, and frontline amateur research — follow along with us on humankind’s greatest, and still escalating, adventure.”

The magazine is making its eight-page timeline article of these decades available as a free PDF file: A Lifetime of Science and Skywatching.
