Cosmology's Best Standard Candles Get Even Better
May 18, 2009
The international Nearby Supernova Factory based at the U.S. Department of Energy's Lawrence Berkeley National Laboratory 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.
