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:
“Let the stars of its dawn be dark; let it hope for light, but have none; may it not see the eyelids of the morning—”
—Bible: Hebrew, Job 3:9.
“The sumptuous age of stars and images is reduced to a few artificial tornado effects, pathetic fake buildings, and childish tricks which the crowd pretends to be taken in by to avoid feeling too disappointed. Ghost towns, ghost people. The whole place has the same air of obsolescence about it as Sunset or Hollywood Boulevard.”
—Jean Baudrillard (b. 1929)
“A woman with her two children was captured on the steps of the capitol building, whither she had fled for protection, and this, too, while the stars and stripes floated over it.”
