The search for life on other worlds: Suzuki Shino discusses the importance of microbiology in searching for habitable worlds

(A) DCAM3 image of the ejecta created during the SCI impact, with four separate rays of material. (B) ONC optical image of the impact site, with numbers corresponding to the ejecta rays in (A). (C). Change in reflectivity before and after the SCI impact. Darker regions are thought to indicate material ejected from below the surface. (Figure 4 in Arakawa et al., Science 2020.)
