Present-day disk galaxies often exhibit distinct thin and thick disks. The formation mechanisms of the two disks and the timing of their onset remain open questions. To address these questions, astronomers analyzed a statistical sample of 111 edge-on disk galaxies at various periods — up to 11 billion years ago, or approximately 2.8 billion years […]
