Atmosphere
An atmosphere (New Latin atmosphaera, created in the 17th century from Greek ἀτμός "vapor" and σφαῖρα "sphere") is a layer of gases that may surround a material body of sufficient mass, and that is held in place by the gravity of the body. An atmosphere may be retained for a longer duration, if the gravity is high and the atmosphere's temperature is low. Some planets consist mainly of various gases, but only their outer layer is their atmosphere.

Famous quotes containing the word atmosphere:
“A noble soul is not the one that can manage the highest flights but the one that rises very little and falls very little but always dwells in a free, resplendent atmosphere and altitude.”
—Friedrich Nietzsche (1844–1900)
“The base of all artistic genius is the power of conceiving humanity in a new, striking, rejoicing way, of putting a happy world of its own creation in place of the meaner world of common days, of generating around itself an atmosphere with a novel power of refraction, selecting, transforming, recombining the images it transmits, according to the choice of the imaginative intellect. In exercising this power, painting and poetry have a choice of subject almost unlimited.”
—Walter Pater (1839–1894)
“All sound heard at the greatest possible distance produces one and the same effect, a vibration of the universal lyre, just as the intervening atmosphere makes a distant ridge of earth interesting to our eyes by the azure tint it imparts to it.”
—Henry David Thoreau (1817–1862)
