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:
“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)
“Nights, I squat in the cornucopia
Of your left ear, out of the wind,
Counting the red stars and those of plum-color.
The sun rises under the pillar of your tongue.”
—Sylvia Plath (1932–1963)
“If men will believe it, sua si bona norint, there are no more quiet Tempes, nor more poetic and Arcadian lives, than may be lived in these New England dwellings. We thought that the employment of their inhabitants by day would be to tend the flowers and herds, and at night, like the shepherds of old, to cluster and give names to the stars from the river banks.”
—Henry David Thoreau (1817–1862)
