Every year, the Geminids appear in the December sky. This shower of shooting stars is often difficult to see in the city, but it's an excellent opportunity to look up at the sky. The Planetarium is offering an evening of free winter sky observation**, from 5 p.m. to 11 p.m. This year, four planets, the Moon and the constellations emblematic of the winter sky will be visible during the evening of December 13. For the occasion, the museum is also extending its opening hours until 11 pm. With the purchase of a ticket, visitors can discover the Rouge exhibition and view the film duo Celestial Chronicles and One Day on Mars. **Free observation cancelled in the event of cloudy skies.
