Over the last decade, two international teams have used the magnituderedshift relation of type Ia supernovae (SNe) to measure the mass density WM and the cosmological constant WL of the universe. Both teams, using largely independent data sets and independent analysis methods, reach the conclusion that the cosmological constant is non-zero and that the expansion of the universe is accelerating (Riess et al. 1998, Perlmutter et al. 1999).
