Type Ia supernovae are important for measuring the universe because they're bright enough to be seen across large distances and similar enough to be a reference, an an object of known luminosity - but astronomers still don't know what star systems make Type Ia supernovae.Two very different models might explain the possible origin of Type Ia supernovae and different studies support each model.
