Summary

This episode of Ciel & Espace’s monthly astronomy podcast, presented by David Fossé, Sébastien Fontaine, and Cyril, provides a guide to observing the night sky in August 2023. The hosts begin with a historical segment on the 17th-century Jesuit astronomer Giovanni Battista Riccioli, who mapped the Moon and named its craters. They then list the month’s key events: the Sun setting through the Arc de Triomphe in Paris (August 7-9), a lunar-Jupiter conjunction (August 8), the Perseid meteor shower peak (August 12-13), the Milky Way visible after midnight around August 20, and Saturn at opposition (August 27). Practical advice is given for observing the Perseids, including camera settings for astrophotography.
