Cosmology's Best Standard Candles Get Even Better -- A simple new method standardizes the brightness of Type Ia supernovae

The Nearby Supernova Factory has discovered an efficient method for standardizing the intrinsic brightness and thus the distance to the cosmic milestones known as Type Ia supernovae. The discovery underlines the crucial importance of excellent supernovae spectra in the quest to understand dark energy.
