Corona
Corona is the outermost layer of the Sun’s atmosphere. It is visible only during the total eclipse of the Sun, and it extends in all directions from the chromosphere.
Chromosphere
The chromosphere is the middle layer of the Sun. It is a blanket of glowing gases surrounding the Sun and measuring 16,000 kilometers thick. It is known as a thin zone of electrified matter. This zone is not visible because of the very bright light emitted from the chromosphere. However, when there is a total eclipse, it becomes visible.
The photosphere
This layer releases light which reaches the earth.
Core
Convective zone
Radiative zone
Sunspots and Prominences
- Sunspots are areas of cooler gases associated with disturbances on the Sun’s surface.
- Prominences are arches of gases billowing out of the Sun’s surface
Auroras
Aurora are natural, multicolored lights displays that can primarily been seen at high latitudes, near the north and south poles. They are caused by energetic electrons and protons exciting atoms in Earth’s upper atmosphere.
Solar Flares
- A solar flare is a sudden flash of brightness observed near the Sun's surface
