Three researchers behind the discovery that our Universe's expansion is accelerating have been awarded this year's Nobel prize for physics.
- o Saul Perlmutter from US
- o Adam Riess also from US
- o Brian Schmidt of Australia
1. The trio( three) studied what are called Type 1a supernovae, determining that more distant objects seem to move faster.
· According to them they suggest that not only is the Universe expanding, its expansion is relentlessly speeding up.
Prof Perlmutter of the University of California, Berkeley, has been awarded half the 10m Swedish krona (£940,000) prize, with Prof Schmidt of the Australian National University and Prof Riess of Johns Hopkins University's Space Telescope Science Institute sharing the other half.
Another imp lists:.
o Prof Perlmutter led the Supernova Cosmology Project, which began in 1988, and Prof Schmidt and Prof Riess began work in 1994 on a similar project known as the High-z Supernova Search Team.
o Their goal was to measure distant Type 1a supernovae - the brilliant ends of a particular kind of dense star known as a white dwarf.
READ CAREFULLY:
Because their explosive ends are of roughly the same brightness, the amount of light observed from the supernovae on Earth should be an indication of their distance; slight shifts in their colour indicate how fast they are moving.
NOTE:
The Nobel prizes have been given out annually since 1901, covering the fields of medicine, physics, chemistry, literature and peace.
Monday's award of the 2011 prize for physiology or medicine went to Bruce Beutler of the US, Jules Hoffmann from France and Ralph Steinman from Canada for their work on immunology.
This year's chemistry prize will be announced on Wednesday oct 4 ,2011.
