protogalaxy
Définition(s)
- 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. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Protogalaxy)
