The Peter and Patricia Gruber Foundation proudly presents the 2007 Cosmology Prize to Saul Perlmutter and Brian Schmidt, and to the Supernova Cosmology Project and the High-z Supernova Search teams, for their discovery that the expansion of the Universe is currently accelerating.
These observations required the development of new techniques that use supernovae exploding within distant galaxies to measure precise distances across a large fraction of the observable Universe.
The discovery of the accelerated expansion has radically changed our perception of cosmic evolution.
