Summary

This episode of the Ciel & Espace podcast presents the celestial events visible in May 2021. The hosts, Cyril Birnbaum and Sébastien Fontaine, guide listeners through the month’s highlights: Mercury’s evening apparition starting May 2, the conjunction of the Moon and Jupiter on May 5, the close approach of the waning crescent Moon and Mercury on May 13, and a total lunar eclipse on May 26 visible from the Pacific region. They also provide detailed advice for observing the Moon’s surface features, particularly along the terminator, and for photographing the crescent Moon and Mercury together. Sébastien Fontaine shares a historical segment on the 15th-century astronomer Ulugh Beg and his observatory in Samarkand. The episode includes a tour of several globular clusters (M13, M3, M5, M92) and a practical astrophotography tip for capturing light trails from cars. The tone is educational and accessible, aimed at amateur astronomers.
