A new white dwarf has been discovered (poetically named: ZTF J1901+1458) that’s doing some stuff that no white dwarf should ever be able to do. In fact, it has multiple properties that are so extreme that it almost certainly did NOT form in the way that we thought all white dwarfs formed. This one peculiar point of faint light may change our understanding of all cosmology.
