Accelerating Universe
Distant supernovae are dimmer than expected (1998): the expansion of the universe is speeding up, which points to dark energy.
Open in the interactive tree →Two teams (Perlmutter; Schmidt and Riess) used type Ia supernovae as standard candles and shared the 2011 Nobel Prize. Dark energy now makes up about 70% of the cosmos, and new surveys such as DESI test whether it changes over time.
