What lies beyond Neptune? Known as the Kuiper Belt, this region may be home to “Planet Nine.” Probes from the Pioneer program, launched in the 1970s, are already there, providing fragments of information about this environment. To help shed light on the subject, Hugues Lacombe, founder of the Club d’astronomie de Charlevoix and an experienced stargazer, will review what we know about this distant region of the solar system and discuss ongoing research. Free admission. No registration required. Seating is limited to the room’s capacity.
