More along, you should come upon large clusters of very hot, young stars. Some could well be many moments a lot more massive than the Sunshine, shining with fierce brilliance still destined to die in mere an incredible number of a long time—cosmic fireflies in comparison to the Sunshine’s regular ten-billion-year everyday living.
