Since 1992, we have been discovering high-redshift supernovae to extend the Hubble diagram to distances where we can measure the impact from the mass density (Omega_M) and the density associated with the cosmological constant (Omega_Lambda). This led to the 1998 discovery of the accelerating Universe. The discovery was awarded the Nobel prize in 2011.
