Figure . Conceptual diagram of the process by which formaldehyde (H2CO) is formed in the atmosphere on ancient, warm Mars and converted into the material molecules of life in the ocean (©Shungo Koyama). A research group led by Shungo Koyama, a PhD student, and Prof. Naoki Terada in this laboratory, estimated the amount of formaldehyde produced in the ancient Martian atmosphere using a photochemical model of the atmosphere, and showed that formaldehyde was continuously produced in the warm period of ancient Mars. The results of this study suggest that sugar, a material molecule of life represented by ribose, one...

A research team led by Professor Shohei Aoki of the Department of Complex Science and Engineering, Graduate School of Frontier Sciences at the University of Tokyo and Project Researcher Tatsuya Yoshida of this laboratory has revealed that carbon monoxide in the Martian atmosphere is low in carbon-13*1 using observation data from the European Mars Explorer ExoMars Trace Gas Orbiter This is the main component of the Martian atmosphere. This is thought to be because carbon 12 is more selectively destroyed when carbon dioxide, the main component of the Martian atmosphere, is decomposed into carbon monoxide by solar radiation. Organic matter...
