Welcome to the night sky report for September 2026 -- Your guide to the constellations, deep sky objects, planets, and celestial events that are observable during the month. This month, the Moon passes near the Teapot - a group of stars in Sagittarius, Venus reaches peak brilliance, the seasons change, and the Harvest Moon meets up with some planetary neighbors. Also this month, Pegasus becomes increasingly prominent in the southeastern sky, allowing skywatchers to locate globular clusters M2 (NGC 7089), M30 (NGC 7099), as well as a nearby double star, Alpha Capricorni, which is an optical double (but not a binary pair). The night sky is truly a celestial showcase. Get outside and explore its wonders from your own backyard.
