Where do the elements in the sun's atmosphere come from?

Answer 1

• Any elements in the sun's atmosphere other than hydrogen or helium were provided by earlier supernovas that exploded before the sun formed.
• The hydrogen and much of the helium in the sun's atmosphere originated directly in the big bang and have not changed since then.
• Some of the helium in the sun's atmosphere passed up in convection currents from the sun's core where it is fusing hydrogen to helium.

Answer 2

The elements in the Sun's atmosphere come from nuclear fusion reactions that occur in its core. Hydrogen nuclei combine to form helium, releasing energy in the process. This energy heats up the Sun and causes it to emit light and heat.
