Discover what you can expect to see during the lunar eclipse and pick up some viewing tips. Gravitational-wave detectors on Earth cannot sense the gravitational-waves from supermassive black hole mergers — learn how observing millisecond pulsars may enable scientist to detect them. Check out the 21 new products S&T's editors consider to be 2019's most interesting. Plus, learn about the characteristics of our nearest stellar neighbors. Do you know who the first professional woman astronomer was? This issue has the answer. Check out our observing picks for the month, explore the secrets of a young and mysterious meteor shower, and observe objects at their highest in the night sky! Read about one amateur astronomer's project to build a folded Serrurier refractor. We also have a sky tour of stars and star clusters to view from light polluted suburban skies.
