The Sun
By Mackenzie Estes
Core
The core is the innermost layer of the sun.
Radiative Zone
The second innermost layer right outside of the core and accounts for 45% of the suns radius.
Convective Zone
In the convection zone, hot plasma rises, cools as it nears the surface, and falls to be heated and rise again.
Photosphere
The photosphere is the visible surface of the Sun that we are most familiar with.
Chromosphere
The chromosphere is a layer of the sun that is 2,000-3 000 kilometers thick. Located above the photosphere, reddish glows can only be seen easily in a total solar eclipse when the photosphere is blocked by the moon.
Corona
A corona is an aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometers into space and is most easily seen during a total solar eclipse, but it is also observable with a corona-graph.
Sunspots
A sunspot is a spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundings. Sunspots show up because the surrounding area is much hotter than the said sunspot.
Prominence
Also called solar prominence. Astronomy. aneruption of a flame like tongue of relatively cool,high-density gas from the solar chromosphere into the corona where it can be seen during a solar eclipse or by observing strong spectral lines in its emission spectrum.
Flare
A sudden eruption of magnetic energy released on or near the surface of the sun, usually associated with sunspots and accompanied by bursts of electromagnetic radiation and particles.Ultraviolet and x-ray radiation from solar flares often induce electromagnetic disturbances in the earth's atmosphere.
Aurora
A natural electrical phenomenon characterized by the appearance of streamers of reddish or greenish light in the sky, usually near the northern or southern magnetic pole.
