The happy face is made of dark areas on the sun. What are they?
NASA/GSFC/SDO
The sun is so hot, it’s cool!
Burning Star
The sun is a star. It is burning hot!
The sun is not solid. It is made of gas and plasma. Plasma is an extra-hot gas that all stars are made from.
Cool Areas
The sun is not the same temperature in every place. The temperature can change as the gas and plasma move around.
The dark areas are places that are cooler than the rest of the sun. That makes them not as bright. They can pop up in different places. This time, they showed up looking like a happy face!
Seeing the Smile
You can see the dark areas only through special telescopes. You can’t see them when you just look up at the sun. (But don’t do that! It’s really bad for your eyes.)
