Evidence
Evidence for Type Ia Supernova Evidence
Independent supernova teams found a consistent departure from matter-only decelerating models. Larger modern samples, combined with CMB and baryon acoustic oscillation data, continue to support late-time acceleration while allowing increasingly detailed tests of dark-energy models.

Type Ia supernovae can be standardized as distance indicators because their light-curve shape and color correlate with intrinsic luminosity.
