The Dark Energy Survey looked at 5000 square degrees of the southern skies in an attempt to characterize dark energy but the observations taken are also very useful for supernovae research. By measuring the standard candles known as Type 1a Supernovae, astronomers can measure the expansion rate of the universe, something that has proven problematic as our observations and equipment have improved.
