The accelerated expansion of the universe is inferred from the relationship between luminosity distance and redshift. This relationship was determined to sufficiently high redshift by two teams in 1998 using type Ia supernovae as standard candles: the High-Z Supernova Search Team and the Supernova Cosmology Project. Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess were awarded the 2011 Nobel Prize in physics for this work.
