TermDefinition
Nuclear Fusion A nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy
Sunspot A spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundings
Solar Flares A brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth
Prominence The state of being important or famous
Corona The rarefied gaseous envelope of the sun and other stars. The sun's corona is normally visible only during a total solar eclipse when it is seen as an irregularly shaped pearly glow surrounding the darkened disk of the moon
Chromosphere A reddish gaseous layer immediately above the photosphere of the sun or another star. Together with the corona, it constitutes the star's outer atmosphere
Photosphere The luminous envelope of a star from which its light and heat radiate.
Convection Zone The convection zone of a star is the range of radii in which energy is transported primarily by convection. In the radiation zone, energy is transported by radiation
Radiative Zone The radiation zone or radiative zone is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion, rather than by convection.
Core The tough central part of various fruits, containing the seeds.
Radiative Of, relating to, or occurring through radiation
Convection the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
