The Full Story
Saul Perlmutter and the Supernova Cosmology Project found that distant Type Ia supernovae were dimmer than expected in 1998. Similar work by other teams reached the same conclusion: the expansion of the universe is accelerating. This discovery implied the presence of dark energy, now thought to make up most of the cosmos. Perlmutter shared the 2011 Nobel Prize in Physics for the breakthrough.
