Saul Perlmutter Biography and Timeline

First Seven High-z Supernova Constraints

Perlmutter and the Supernova Cosmology Project publish cosmological constraints from an initial sample of seven high-redshift Type Ia supernovae.

Accelerating Expansion Announced

Perlmutter publicly presents Supernova Cosmology Project evidence that the expansion of the universe is not being halted by gravity and is instead accelerating.

Dark Energy

Perlmutter measures distant supernovae indicating that cosmic expansion is accelerating

Accelerating Universe

Reports supernova evidence that cosmic expansion is accelerating.

Role range: 1959-

Forty Two Supernova Cosmology Result

Perlmutter and collaborators publish the Supernova Cosmology Project analysis of 42 high-redshift supernovae, strengthening evidence for an accelerating universe.

Nobel Prize for Accelerating Universe

Perlmutter receives half of the 2011 Nobel Prize in Physics for discovering the accelerating expansion of the universe through observations of distant supernovae.
