The region of "altered space" that will interact with the magnetic properties of a magnet. It is located mainly between the opposite poles of a magnet or in the energetic space about an electric charge in motion.
Industry:Astronomy
An instrument carried to Jupiter on the Galileo planetary spacecraft, imaging in regions of the energy spectrum that humans cannot see. NIMS website at the Jet Propulsion Laboratory.
Industry:Astronomy

Industry:Astronomy
An element with atomic number 6; symbol: C. Graphite is a low-pressure form of carbon. Diamond is a high-pressure form of carbon. (Carbon is one of the four elements essential for life. The others are hydrogen, oxygen, and nitrogen. )
Industry:Astronomy
The process by which plants convert water and carbon dioxide into carbohydrates, using sunlight as the source of energy and the aid of chlorophyll.
Industry:Astronomy
The mean Earth-Sun distance, equal to 149. 5 million kilometers or 93 million miles.
Industry:Astronomy
The buildup of heavy isotopes inside massive stars by the slow (hence the use of "s") absorption of neutrons by atomic nuclei. See also r-process and supernova.
Industry:Astronomy
Geochemical and physical processes that result in the sequential formation and separation of minerals from a melt. The residual magma changes in composition and becomes enriched in incompatible elements.
Industry:Astronomy
Water movement due to differences in the density of the water from place to place usually caused by changes in the amount of material held in suspension or changes in temperature or variations in salinity.
Industry:Astronomy
Common mineral; ranges from NaAlSi<sub>3</sub> O<sub>8</sub> (albite) to CaAl<sub>2</sub> Si<sub>2</sub> O<sub>8</sub> (anorthite).
