When JWST peered into the young universe at redshifts of 6–10, it revealed a scattering of mysterious 'little red dots' (LRDs). These objects combined features of galaxies and active nuclei, but their spectra refused to fit into familiar patterns.

Around every galaxy lies an invisible corona of cold gas. It extends far beyond the stellar disk and serves both as a fuel depot for new stars and as a graveyard for ejected material.
