|Detail||：||Deep and ultra wide field of view image from Hyper Suprime-Cam mounted on the Subaru Telescope including a large spiral galaxy M81, M82, dwarf galaxy Holmberg IX and NGC 3077. The research team's analysis revealed the trace of its past interactions with the neighboring galaxies. It is exciting to see the evidence of the hierarchical galaxy assembly process at this distance beyond the Local Group of galaxies.
