As galaxies form and evolve in the Universe, they leave behind a complex trail of ultra-faint stars and gas in their outskirts. This faint material holds clues to the growth and accretion history of galaxies. In this colloquium, we present some of the deepest images of the faint universe, of dwarf and massive galaxies, as seen in X-ray, optical and radio wavelengths. We discuss how these images help us understand the key physical and environmental processes such as star formation, feedback and mergers that drive the growth of galaxies big and small. These results demonstrate the importance of preserving low surface brightness structure in the next generation of surveys from Euclid, Rubin-LSST, Roman and SKA in order to further our understanding of galaxies across the Universe.
