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:
“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)
“The sage as astronomer.—As long as you still experience the stars as something “above you,” you still lack viewpoint of knowledge.”
—Friedrich Nietzsche (1844–1900)
“Doubt thou the stars are fire,
Doubt that the sun doth move,
Doubt truth to be a liar,
But never doubt I love.”
—William Shakespeare (1564–1616)
