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:
“I, who had heard of music in the spheres,
But not of speech in stars, began to muse:
But turning to my God, whose ministers
The stars and all things are; If I refuse,
Dread Lord, said I, so oft my good;
Then I refuse not ev’n with blood
To wash away my stubborn thought:
For I will do or suffer what I ought.”
—George Herbert (1593–1633)
“Art thou pale for weariness
Of climbing heaven and gazing on the earth,
Wandering companionless
Among the stars that have a different birth,”
—Percy Bysshe Shelley (1792–1822)
“The stars which shone over Babylon and the stable in Bethlehem still shine as brightly over the Empire State Building and your front yard today. They perform their cycles with the same mathematical precision, and they will continue to affect each thing on earth, including man, as long as the earth exists.”
—Linda Goodman (b. 1929)
