Daniel K. Inouye Telescope, Gravitational-Wave Background, and Planetary Imaging

In the November issue of Sky & Telescope, we celebrate the discovery of the gravitational-wave background, made thanks to decades-long observations of pulsars. We’re also lauding the first images from the Daniel K. Inouye Telescope, which has just completed its first year of science observations. Over the next several decades, the telescope promises to revolutionize our understanding of the Sun. Also in this issue, learn about the Antikythera Mechanism, an ancient melding of mathematics and engineering designed to aid understanding of the solar system. Dive into the solar system yourself with a primer on planetary imaging. But don’t put the magazine down until you read about salt and its role in the solar system — and in our search for life.
