Polaris, Spinning Scopes & the Herschel Hustle

Explore the sky near and far with the March 2019 issue of Sky & Telescope. S&T Editor Camille Carlisle takes on Polaris, revealing how much we do and don't know about the northern star, while author Benjamin Skuse walks us through the dynamics of scopes in space. Speaking of which, data from the Gaia spacecraft are helping solve a longstanding controversy over the distance to the Pleiades. Looking for more to observe these winter nights? Take a page out of amateur and expert Tom Reiland's book and observe some (or all) of the 2,477 deep-sky objects in the Herschel catalog! Or, for those interested in an easier stroll through the sky, take a peek at the planets greeting us at dawn. Enjoy these and other stories in the March 2019 issue of Sky & Telescope.
