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:
“Ere he was born, the stars of fate
Plotted to make him rich and great:
When from the womb the babe was loosed,
The gate of gifts behind him closed.”

And tremble, and look mild as amber;
When wicks are lighted in the chamber
You might say stars were settling there.”

Of your left ear, out of the wind,
Counting the red stars and those of plum-color.
The sun rises under the pillar of your tongue.”
