Sphere (novel), a 1987 book written by Michael Crichton

The biosphere is the part of the earth, including air, land, surface rocks, and water, within which life occurs, and which biotic processes in turn alter or transform. From the broadest biophysiological point of view, the biosphere is the global...

A magnetosphere is the region around an astronomical object in which phenomena are dominated or organized by its magnetic field. Earth is surrounded by a magnetosphere, as are the magnetized planets Jupiter, Saturn, Uranus and Neptune. Mercury and...

Celestial sphere, the astronomical description of the sky

A corona is a type of plasma "atmosphere" of the Sun or other celestial body, extending millions of kilometres into space, most easily seen during a total solar eclipse, but also observable in a coronagraph. The Greek root of the word Corona means...

The troposphere is the lowest portion of Earth's atmosphere. It contains approximately 75% of the atmosphere's mass and almost all of its water vapor and aerosols. The average depth of the troposphere is about 11 km in the middle latitudes. It is deeper...

The lithosphere (IPA: [ˈlɪθ.ə.sfiɹ], from the Greek for "rocky" sphere) is the solid outermost shell of a rocky planet. On the Earth, the lithosphere includes the crust and the uppermost mantle which is joined to the crust across the Mohorovičić...

SPHERE, Spectroscopic and Polarimetric High-contrast Exo-planet REsearch, an instrumentation project at the VLT to directly image extrasolar planets

The asthenosphere (from an invented Greek ἀσθενός a + ''sthenos "without strength") is the region of the Earth between 100 and 200 km below the surface — but perhaps extending as deep as 400 km — that is the weak or "soft" zone in...

A hydrosphere (Greek hydro means "water") in physical geography describes the collective mass of water found on, under, and over the surface of a...

Spheres (anime), a Korean anime

Sinosphere, also known as Chinese world, Chinese cultural sphere or Chinese-character cultural sphere , is a grouping of countries and regions that are currently inhabited with a majority Chinese population or were historically under heavy Chinese...

The stratosphere is the second layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near...

Sphere (film), a 1998 film based on the 1987 novel, starring Dustin Hoffman, Sharon Stone and Samuel L. Jackson

Megaspherulites

Sphere of influence, a metaphorical region of influence surrounding a person, concept, country etc.

The mesosphere (from the Greek words mesos = middle and sphaira = ball) is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the thermosphere. The mesosphere is located from about 50 km to 80-90 km altitude...

Noosphere, the sphere of human thought and/or creativity

Lapidary spheres

Cultural region, such as:

The thermosphere is the layer of the earth's atmosphere directly above the mesosphere and directly below the exosphere. Within this layer, ultraviolet radiation causes ionization. (see also: ionosphere). It is the fourth atmospheric layer from earth....

Sphere (program), a cross-platform open-source computer program for making role-playing games

Stone spheres of Costa Rica

The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep (approximating to, if a little less than, the diameter of the Earth). The chromosphere is more visually...

The photosphere of an astronomical object is the region from which externally received light comes. It extends into a star's surface until the gas becomes opaque, equivalent to an optical depth of 2 or 3. In other words, the photosphere is the region...

Artificial stone spheres (Petrospheres)

Indosphere is defined as "a socio-political sphere subsuming those countries, cultures, and languages that have historically been influenced by the politics, culture, religion, and languages of India." Beyond the Indian subcontinent, mainland Southeast...

The term Geosphere is often used to refer to the densest parts of Earth, which consist mostly of rock and regolith. [1]. The term originally applies to the four nested geospheres identified since Meteorology (Aristotle) with the states of terrestrial...

Stone round shot (cannonballs)

The exosphere is the uppermost layer of the atmosphere. On Earth, its lower boundary at the edge of the thermosphere is estimated to be 500 km to 1000 km above the Earth's surface, and its upper boundary at about 10,000 km. It is only from the exosphere...

Sphere Books, a British paperback-publisher from the 1960s to the 1980s

A sphere is an object shaped like the surface of a ball, but can be used to refer to a ball-shaped object, as well as a sphere-like or annular region or shell. Additionally, it has several metaphorical uses. In mathematics:

Hypersphere or n-sphere, the set of points which are a fixed distance from a central point in a space of n+1 dimensions

Celestial or planetary spheres, referring to a geocentric model of the universe and the associated postulate of a music of the spheres

In Earth and planetary science, various systems with a planetary scale extension:

Atmosphere, including the Earth's atmosphere and Celestial body atmospheres

In stellar physics, the layers of a star, in particular of the Sun:
