To simulate 13.5 billion years in the life of a single disk galaxy, NASA needed more than your average desktop PC. The memorable video below is the direct work of the agency's Pleiades supercomputer and, by NASA's estimates, approximately 1 million CPU hours. The resulting 2:17 clip is nothing short of captivating, beginning shortly after the Big Bang and running through present day. It wouldn't be a disk galaxy without an abundance of stars, and each of the colors in the simulation represents something different: red depicts older stars while white and bright blue correspond to new ones — the paler blue shade accounts for distribution of gas density.

pas besoin de son , ni d'english spoker
les images suffisent , c'est très pédagogique , merci ! -
Mais parfaitement Janelle oui et c'est super d'apprecier oui c'est la première fois qu'un tel calcul et une telle visualisation a été réalisé c'est grâce au supercalculateur Pléiades au centre de recherches Ames NASA @ Moffett Field, Calif près de San Francisco où j'ai encore quelques amis ...
Merci to you Janelle
