Computer graphics movie of the star formation history in the galaxy MACS1149-JD1, 13.2 billion years away from Earth. One of the most distant galaxies ever known.

The self-gravitating nature of matter creates filamentary structures and the density at the intersections of the filaments increases. Around 200 million years after the Big Bang, active star formation ignites in the high density regions, which leads to the formation of galaxies. The gas in the galaxy is blown off by active stellar wind and supernovas, then the gas returns to the galaxy and causes another burst of star formation.
