Our Bright and Shining Star

The Sun

The importance of the sun

Earth would be a lifeless, frigid planet without the warmth and energy that we get from the sun. The sun provides us with light, heat, and energy, so we wouldn't be able to survive without the literal center of our solar system.

The sun's layers

The inner layers of the sun are the core, the radiative zone, and the convection zone. The outer layers are the photosphere, the chromosphere, and the corona.

What is a sunspot?

Sunspots are darker, cooler regions in the photosphere.

What is a prominence?

A solar prominence is an arc of gas that erupts from the surface from the sun. They are held above the sun's surface by a strong magnetic field.

What is a solar flare?

A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. By definition, it is a sudden, rapid, and intense variation in brightness.

What is an aurora?

An aurora is colored light in the night sky near Earth's poles. It is called the aurora borealis in the northern hemisphere.
