Type Ia supernovae were long ago considered "standard candles" that might be useful for distance measurements. But only in the last decade, with intense and systematic studies undertaken at CTIO and elsewhere, was it realized that this type of supernovae are actually more accurately "standardizable" candles. This refinement led to an era of precision distances that has provided solid evidence of Dark Energy, and has changed the way both astronomers and physicists view the Universe. We'll review the study of supernovae and their use as cosmological tools, both in present experiments such as ESSENCE and SNLS and future projects such as LSST.
