The Sun
The star around which the earth orbits.
The Sun's layers
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona
Core
The central region where nuclear reactions consume hydrogen to form helium
Radiative Zone
The section of the solar interior between the innermost core and the outer convective zone.
Convective Zone
Hot plasma rises, cools as it nears the surface, and falls to be heated and rise again
Photosphere
The lowest layer of the Sun visible from Earth.
Chromospere
The second of the three main layers in the Sun's atmosphere and is roughly 2,000 kilometers deep.
Corona
The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph
Sunspots
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions
Prominence
A large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape.
Flare of the Sun
A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released.
Aurora
The aurora is when charged particles colliding, creating bright lights in the sky.
