Astro Chemistry

~60 min · 15 stations

Astro Chemistry is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify fundamental elements formed during the initial stages of universal expansion; define the composition of gas clouds found between distant star systems; describe how massive stars create heavier elements through nuclear fusion processes.
