Manoa Associate Professor Ralf Kaiser is leading an interdisciplinary group of researchers to study the atmosphere of Saturn’s moon Titan. The study was awarded a five-year $2.4 million grant from the National Science Foundation’s Collaborative Research in Chemistry Program.
Hydrocarbon-based atmospheric layers on Titan that have unique properties allowing for preservation of astrobiologically important molecules may yield vital clues on the chemical composition of the Earth’s atmosphere a few billions of years ago. According to scientists, information gained from analyzing these molecules could also lead to a greater understanding of the origin and chemical evolution of the solar system.
Titan’s atmosphere is considered ideal for providing such scientific understanding because it offers the potential to reconstruct the scene of the primordial terrestrial atmosphere as Titan and proto-Earth are believed to have emerged with similar atmospheres from the Solar Nebula.
