Every quarter, the Sidérales offer the general public the chance to revisit one of the year's highlights in the field of astronomy, alongside researchers fromParis Observatory - PSL. The program includes a lecture and a planetarium session on the theme, followed by outdoor sky observation, weather permitting. On Thursday March 13, 2025, Valéry Lainey will talk about Mimas, a satellite of Saturn, and its ocean.
Discovered in February 2024, the ocean of liquid water beneath Mimas' ice sheet is astonishing to scientists, being a highly cratered, ancient and geologically inactive moon. Valéry Lainey, a specialist in the orbital dynamics of the solar system's moons, will be on hand to discuss the subject, at the Palais de la découverte's Étincelles, for a nocturne starting at 7pm.
It's an opportunity to learn more about our sky, to find out all you need to know about this satellite, and to observe it with specialists!
