The young investigators encounter new challenges, from a mysterious 'black sun' to the harsh realities of a changing climate, and they must work together to understand the science behind what they're seeing. Blending adventure with real-world astronomy and environmental science, their journey reveals just how connected our planet is to the wider universe. Featuring engaging story chapters alongside educational sections on space exploration, climate change, and Antarctic research, Volume 2 expands both the scope and stakes of the CMS team's mission.
