Summary

This episode of Ciel & Espace’s monthly astronomy program, presented by Cyril Birnbaum and Philippe Henarejos, offers a comprehensive guide to observing the night sky in January 2022. The hosts discuss several key celestial events: the Quadrantid meteor shower peaking on January 3, a close approach of the crescent Moon and Jupiter on January 5, Mercury’s greatest elongation on January 7, the reappearance of the zodiacal light from January 20, and a lunar conjunction with Mars on January 29. The program includes practical advice for observers, such as how to locate Mercury using setting circles, how to photograph the crescent Moon and planets, and a special technique for spotting Sirius B, the faint companion of Sirius, using the nearby star Rigel as a guide. The hosts also explain the science behind phenomena like earthshine and the zodiacal light, and mention the historical context of the Quadrantid meteor shower’s now-defunct constellation. The episode is aimed at amateur astronomers and provides both naked-eye and telescopic observation tips.
