Answer» Blue colour INDICATES that the star is the youngest one. Young stars (of blue colour) emit a lot of lightweight than older (redder) stars. However, since there was with reference to abundant\|the maximum amount} lightweight within the young UNIVERSE as there's nowadays - THOUGH the galaxies square measure CURRENTLY MUCH redder - this suggests that there have been fewer stars within the early Universe than nowadays.
