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)
“In my stars I am above thee, but be not afraid of greatness. Some are born great, some achieve greatness, and some have greatness thrust upon ‘em.”
—William Shakespeare (1564–1616)
“Frankie and Johnny were lovers, O lordy how they could love,
Swore to be true to each other, true as the stars above;
He was her man but he done her wrong.”
—Unknown. Frankie and Johnny (l. 1–3)
