Some galaxies hit a point in their lives when their star formation is snuffed out, and they become “quenched.” Quenched galaxies in the distant past appear to be much smaller than the quenched ...

Distance records are an excellent proxy for the state of the art in astronomy. Finding extremely faraway galaxies is hard. In general, objects get smaller and fainter with distance (although bizarre ...
