This Week’s Sky At a Glance

Check out Sky & Telescope’s weekly observing update, Sky at a Glance, published every Friday. Not only do we provide simple sky maps and observing tips for the upcoming week, we also keep you up to date on the latest celestial events.

A winter article might focus on the dazzling Orion Nebula, where thousands of stars are forming in the cloud of gas and dust, only 1,300 light-years away. A spring article could guide you through the small patch of sky in the constellations Cygnus, Lyra, and Draco where the Kepler Space Telescope has found more than 1,000 exoplanets. And a summer article might be bombarded with meteors from the stunning Perseids, which grace us with their presence every August, while a fall article might highlight the lucky alignment of two or more planets in the evening sky.

No matter the week, take a look at Sky at a Glance to catch up on celestial current events.
