Stars
The internal heating within stars are so great that they sustain thermonuclear reaction of hydrogen to helium and can make heavier elements. The Sun for example has a core temperature of 13,600,000 K. The bluer, more massive, hotter, and older the stars are, the more internal heating it has. During the end of its lifecycle, the internal heating of a star increases dramatically, caused by contracting core, eventually becoming hot enough to fuse helium then carbon or oxygen.

Famous quotes containing the word stars:
“Think not, Percy,
To share with me in glory any more.
Two stars keep not their motion in one sphere.”
