Solar - Photosphere

After the Sun's core, radiation zone and convection Zone comes the last part of the sun on the outside.

The photosphere is the outside shell of the sun, the part that we see that gives light to our planet from space.

The photosphere is super hot, at over 10,000 degrees F.

It is mostly made up of things called granules which are huge bubbles of plasma over 600 miles wide!

The granules rise up from the convection zone, then after about 8 minutes they cool off and go back down to a smaller size.
