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:
“With a tongue like a razor he will kiss,
the mother, the child,
and we three will color the stars black
in memory of his mother
who kept him chained to the food tree
or turned him on and off like a water faucet....”
—Anne Sexton (1928–1974)
“While the stars that oversprinkle
All the heavens, seem to twinkle
With a crystalline delight;
Keeping time, time, time,
In a sort of Runic rhyme,
To the tintinnabulation that so musically wells
From the bells, bells, bells, bells,”
—Edgar Allan Poe (1809–1849)
“And yet with neither love nor hate,
Those stars like some snow-white
Minerva’s snow-white marble eyes
Without the gift of sight.”
—Robert Frost (1874–1963)
