Sky & Telescope Highlights

By Monica Young
News Editor, Sky & Telescope



As a magazine, Sky & Telescope serves its readers deep dives into observing and science topics. On our website, Sky & Telescope similarly dives deep into breaking astronomy and observing news. Staff and freelance writers cover a variety of topics, from what to see tonight, to news from the amateur community, to the latest exoplanet discoveries. We then compile these news stories into short-and-sweet pieces for the monthly News Notes department.

In every story, we pride ourselves on delving into the facts behind the headlines and giving context to the newest discoveries for the interested reader — whether they be an amateur, armchair, or professional astronomer.

Read a selection of our stories from the month of October, highlighted below, or visit our website for the latest astronomy news. (And stay tuned for our website’s new look and friendlier feel, coming in January!)
