July Skywatching Guide: From Buck Moons to Meteor Showers

The night sky this July offers a dense calendar for observers, featuring a sequence of planetary conjunctions, the peak of the Southern Delta Aquariid meteor shower, and the optimal window for viewing the Milky Way’s luminous core as it stretches across the southern horizon throughout the month.

The celestial display kicks off in the early hours of July 7 and 8, when the third-quarter moon and Saturn hover near the eastern horizon. Mars and the Pleiades star cluster join this alignment just before dawn. By July 11, the crescent moon shifts to form a distinct triangle with Mars and the Pleiades; astronomers recommend binoculars to resolve the cluster’s finer details during this pre-dawn window.

Darkness becomes a primary asset on July 14, the date of the new moon. With minimal lunar interference, the galactic core of the Milky Way becomes significantly more prominent, particularly for those positioned in remote areas such as national parks. The month’s planetary pairings conclude on July 17, as Venus and the crescent moon appear briefly above the western horizon shortly after sunset.

The month closes with two major events. The full "buck" moon, named for the seasonal growth of deer antlers, reaches peak brightness on July 29. While the precise peak occurs at 10:30 am ET, the most striking views are expected during the evenings of July 28 and 29. Finally, the Southern Delta Aquariid meteor shower reaches its maximum activity during the predawn hours of July 30 and 31, marking the end of a busy cycle for stargazers.
