Celestial Atmospheres is a series that considers the atmospheric layers of planets, stars, and other celestial bodies as records of information essential to understanding the nature and evolution of the cosmos. The study of these atmospheres, together with observations made through space‑based telescopes, contributes to a deeper understanding of planetary formation and the conditions linked to the origins of life on Earth. Across interstellar space, the layered envelopes of celestial bodies function as records of physical processes, preserving evidence of transformation over cosmic timescales and expanding our comprehension of the universe.
