Undergraduate student may have solved puzzle regarding isolated galaxies that have stopped producing stars

An undergraduate astrophysics student at UC Berkeley has discovered three isolated galaxies that have stopped producing stars, a rare combination that sheds light on a long-held astronomical theory. This finding is significant for sky-watchers because it provides new insights into the life cycles of galaxies and how they interact with their surroundings. The discovery of these unusual galaxies, known as Shapiro Dwarf Galaxies I, II, and III, offers a unique opportunity to study the conditions that lead to the cessation of star formation in galaxies.
