Supernovae - Astrophysicist Saul Perlmutter

Exploring Supernovae Leads To Physics Nobel Prize


Astrophysicist Saul Perlmutter is part of the team that was awarded the 2011 Nobel Prize in physics for the discovery that the expansion of the universe is not slowing down but is accelerating. The results of that research suggest the universe is filled with dark energy.

The universe is expanding even faster than expected

Hubble Space Telescope astronomers have discovered that the universe is expanding 5-9% percent faster than expected. They made the discovery by refining the universe's current expansion rate to unprecedented accuracy, reducing the uncertainty to only 2.4%. The team made the refinements by developing innovative techniques that improved the precision of distance measurements to faraway galaxies. These measurements are fundamental to making more precise calculations of how fast the universe expands with time, a value called the Hubble constant. Ref. Source 8u.
