Protogalaxy
From Wikipedia, the free encyclopedia
For the 2010 action-adventure video game, see ProtoGalaxy.
In physical cosmology, a protogalaxy, which could also be called a "primeval galaxy", is a cloud of gas which is forming into a galaxy. It is believed that the rate of star formation, during this period of galactic evolution, will determine whether a galaxy is a spiral or elliptical galaxy; a slower star formation tends to produce a spiral galaxy. The smaller clumps of gas in a protogalaxy form into stars. The term protogalaxy was[citation needed] mainly used in the Big Bang Theory.
