Astrobiology Study using ALMA – Are Icy Worlds in our Solar System Habitable?

At an altitude of 5,000 m, ALMA is the largest astronomical observing facilities existent. Consist of 66 12‐m and 7‐m antennas, ALMA acts as a single telescope with variable diameters of 150 m to 16 km. ALMA is designed to address some of the most profound questions of our cosmic origins including the origins of life itself.

Are we alone? In this summer, our research projects will be mainly astrobiology oriented – based on our ALMA observations.

Identification of subsurface oceans and search for potential signatures of life on icy solar‐system bodies. By measuring the salinity (or chlorinity) and the oxidation state using ALMA, we will advance our knowledge significantly on the habitability of the icy worlds in our Solar System, including Galilean moons Io, Europa, anymede and Callisto, and the dwarf planet Ceres.

We’d like to identify a few talented students who are interested in astrobiology study to learn more about the origins and evolution of life on Earth and elsewhere in the universe. We welcome determined students who are willing to devote their time for research in this summer. Qualified applicants should have a strong interest in scientific research; however, backgrounds in chemistry, life science, and/or biology are not required.
