Resumo: Empirically, Type Ia supernovae are the most useful, precise, and mature tools for determining
astronomical distances. Acting as calibrated candles they revealed the presence of dark energy
and are being used to measure its properties. However, the nature of the Type Ia explosion,
and the progenitors involved, have remained elusive, even after seven decades of research. But
now, new large surveys are bringing about a paradigm shift—we can finally compare samples
of hundreds of supernovae to isolate critical variables. As a result of this, and advances in
modelling, breakthroughs in understanding all aspects of these supernovae are finally starting
to happen
