Chronological sequence of stellar evolution
WebAll of the hydrogen and most of the helium in the universe emerged 13.8 billion years ago from the Big Bang. The remainder of the chemical elements, except for a tiny amount of … WebEvolution of the Sun evolution of a Sun-like star The Sun has been shining for 4.6 billion years. Considerable hydrogen has been converted to helium in the core, where the burning is most rapid. The helium remains there, where it absorbs radiation more readily than hydrogen. This raises the central temperature and increases the brightness.
