What Does The Life Of A Galaxy Look Like

The life of a galaxy is not really something that would be top of everyone’s list of things to check out. However, when you consider it this is something truly amazing and to help us understand NASA have produced a video showing the 13.5 billion year lifespan.

According to NASA Goddard who posted the video, this is what is happening;

This cosmological simulation follows the development of a single disk galaxy over about 13.5 billion years, from shortly after the Big Bang to the present time. Colours indicate old stars (red), young stars (white and bright blue) and the distribution of gas density (pale blue); the view is 300,000 light-years across. The simulation ran on the Pleiades supercomputer at NASA’s Ames Research Centre in Moffett Field, Calif., and required about 1 million CPU hours. It assumes a universe dominated by dark energy and dark matter.
