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:
“And now the sparrows warring in the eaves,
The curd-pale moon, the white stars in the sky,
And the loud chaunting of the unquiet leaves,
Are shaken with earth’s old and weary cry.”
—William Butler Yeats (1865–1939)
“The faery beam upon you,
The stars to glisten on you,
A moon of light
In the noon of night
Till the firedrake hath o’er gone you.”
—Ben Jonson (1572–1637)
“Then, that no region of the universe
Should remain void of life, the floor of heaven
Was peopled with the stars and godlike forms,
The seas became the abode of glittering fish.
Earth took the beasts and mobile air the birds.
A holier animal was wanting.”
—Ovid (Publius Ovidius Naso)
