Summary

This episode of Ciel & Espace’s monthly sky guide for December 2024 highlights Jupiter at opposition on December 7, making it the dominant object in the night sky. The hosts, David Fauqué, Cyril Birnbaum, and Sébastien Fontaine, discuss key celestial events: a thin crescent Moon setting near Venus on December 4, a conjunction of Saturn and the Moon on December 8, the Moon passing near Jupiter on December 14 and Mars on December 17, and Mercury at its greatest western elongation on December 25. Sébastien opens with a historical and explanatory segment on lunar phases, clarifying the difference between sidereal and synodic periods, and why some years have 13 full moons. Cyril provides practical photography tips, including using smartphones for the Moon-Venus event and video techniques for capturing Jupiter’s details. The episode also offers advice for observing Mars, noting its upcoming opposition in January 2025 but with less favorable conditions. The hosts mention the BepiColombo spacecraft’s recent flyby of Mercury. The show concludes with a photography challenge related to a Christmas gift idea, focusing on a common issue with tripod heads.
