The sun

the star around which the earth orbits.

layers of the sun

The temperature in the chromosphere varies between about 4000 K at the bottom , so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun

layers of the sun

Photosphere - The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.
Corona - The corona is the outermost layer of the Sun.
Transition Region - The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona.
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.

sun spots

Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions.


A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape


A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released.


An aurora, sometimes referred to as a polar light, is a natural light display in the sky
