Comet Leonard, Venus, and Springtime Galaxies
In the May 2022 issue of Sky & Telescope, we’re displaying some of the incredible images and sketches of Comet Leonard (C/2021 A1) sent to us by our readers. We also discuss a possible new meteor shower from the broken pieces of Comet 73P/Schwassmann-Wachmann. Plus, Venusian science is on the rise with three new missions heading to Earth’s sister planet in the next decade. So if you haven’t taken a look at the second planet from the Sun in some time, it’s time to break out those binoculars. We also have a fantastic selection of springtime binocular galaxies to enjoy while you wait for Venus to appear over the horizon alongside Jupiter a few hours before the Sun this month. Also in this issue, we present a cosmology conundrum for you to mull over: Why don’t the oldest stars have as much lithium as current estimates say they should?
