July 2025: Meteor Showers, Sky Events, and Surveys

July 2025 offers several notable astronomical events, including the Buck (or Thunder) Moon on July 10, visible worldwide. Mercury reaches its greatest eastern elongation on July 4, providing an excellent viewing opportunity. A rare alignment of the moon, Saturn, and Neptune occurs on July 16. The end of July features a double meteor shower—Southern Delta Aquariids and Alpha Capricornids—peaking July 29-30 with up to 30 meteors per hour and bright fireballs. Around the new moon on July 24, the Milky Way and prominent star clusters like the Pleiades and Messier 4 are especially visible. The Rubin Observatory in Chile is preparing to start a decade-long sky survey, while regions in the far north continue to experience the Midnight Sun phenomenon.
