Caltech team creates simulation of Milky Way's birth
Astronomers at the California Institute of Technology have created a computer simulation of the Milky Way's formation, using 2,000 computers combining for a total of 7,00,000 CPU hours. The simulation has removed previous confusions that the galaxy should be surrounded by thousands of dwarf galaxies while actually there are 30, claiming that many galaxies were blown away by exploding stars.
