A Harvest Moon with 5 planets on the side: September is the best month for stargazing, and this year is extra special
Generally mild weather and increasing hours of darkness make September a great month for observing, and this year, there's a particularly busy sky.
September is the prime time for stargazing as warm evenings are accompanied by longer, darker nights. The Milky Way remains visible overhead, and the changing seasons may increase the chances of spotting the northern lights. In the Northern Hemisphere, days get shorter and nights become longer with the autumn equinox on September 22, making it the ideal time for celestial viewing.
During September, there are five planets visible to the naked eye: Venus and Mercury in the evening, Mars and Jupiter in the morning, and Saturn visible throughout the night. Neptune reaches opposition on September 26, providing a close and direct viewing opportunity. The moon passes close to several bright planets, creating additional viewing chances.
The full Harvest Moon rises on September 26, following shortly after Saturn. This is one of the last opportunities for Northern Hemisphere observers to witness the brightest parts of the Milky Way in the evening as the star-rich regions of Sagittarius and Scorpius descend towards the western horizon. The Great Square of Pegasus rises in the East, signaling the arrival of the autumn sky. With numerous cosmic attractions, September is undoubtedly a prime month for stargazers.
