Cosmic Transition from Deceleration
Riess uses very distant Type Ia supernovae to identify evidence that the universe once decelerated before dark energy became dominant and expansion began accelerating.

Riess uses very distant Type Ia supernovae to identify evidence that the universe once decelerated before dark energy became dominant and expansion began accelerating.
Riess uses distant Hubble supernovae to trace acceleration farther back in time and strengthen evidence that dark energy behaves approximately like a cosmological constant.
Riess improves the Hubble constant measurement, reducing the range of dark-energy models allowed when local expansion data are combined with early-universe observations.
Begins long-term Hubble monitoring of Jupiter through the Outer Planet Atmospheres Legacy program.
Hubble measurements show Jupiter's Great Red Spot has shrunk to its smallest size then recorded.
