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:
“It was like passing a boundary to dive
Into the sun-filled water, brightly leafed
And limbed and lighted out from bank to bank.
That’s how the stars shine during the day.”
—Wallace Stevens (1879–1955)
“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)
“The stars move still, time runs, the clock will strike,
The devil will come, and Faustus must be damned.
O I’ll leap up to my God: who pulls me down?
See, see, where Christ’s blood streams in the firmament.
One drop would save my soul, half a drop, ah my Christ.”
—Christopher Marlowe (1564–1593)
