Sky & Telescope January 2024 Magazine

In the January issue, we’re gearing up for the North American eclipse that’s now only four months away. We dive into the history of the Saros cycle, a pattern that enabled ancient Babylonians to predict eclipses. We also explore how modern people can participate in ongoing eclipse-related science, like recording how the animal life around us reacts to these incredible events. Next, we’re championing a return to dark skies as we look at how the irresponsible use of outdoor lighting and LEDs has affected not only our enjoyment and exploration of the night sky but also the plant, insect, and wildlife around us — including the effects on the human body. Finally, we tie things up with a guide to purchasing a beginner’s astrophoto system.
