When a dense accumulation of these nebula gathers, the mass becomes a spawning ground for stars. As this mass of gas and dust heats up, gravity causes it to clump together, and a new star is formed. But only after nuclear fusionCombining of nuclei of two or more lighter elements into one nucleus of a heavier element; the process stars use to produce energy to produce light and support themselves against their own gravity. takes place at the star's core does it produce enough light for us to see it.
