The Eight Layers of the Sun
March 27, 2009
The Sun is Hotter Than Hot!
The Sun's temperature varies over time and throughout these seven layers …
Core
The hottest part of the Sun is the core, at 28,080,000°F, on average.
Radiative Zone
The second layer becomes cooler and is where photon particles carry energy in all directions through a process called radiation.
Tachocline
A thin third layer, the tachocline acts as a border between two differently rotating zones.
Convective Zone
The fourth layer is a zone of boiling, bubbling plasma that transfers energy outward through a process called convection.
Photosphere
The fifth layer is the visible surface where sunspots appear.
Chromosphere
The sixth layer is where the temperature begins to rise again. A thin, reddish layer, the chromosphere is seen only during eclipses or with special solar-viewing equipment.
Transition Region
The layer between the hot corona and cooler chromosphere
Corona
The eighth and outer layer of the Sun gets extremely hot, measuring 1,800,000°F more. This layer extends far into space and is shaped by the Sun's magnetic field, is visible only during eclipses or with special equipment.
Now that's hot!
