How is helium formed
WebWhen they have fused most of their hydrogens into helium, the core is not hot enough to withstand gravity and it collapses. The outer layers expand to form a RED GAINT STAR, much larger than the original star. Other fusion reactions happen inside RED GIANTS, such as combining helium nuclei to form heavier elements. http://www.madehow.com/Volume-4/Helium.html
