a closer look at the Sun

Here's a closer look at the inside of the Sun. Peek beneath the Sun's surface to get a glimpse of its secrets.

This illustration summarizes the main features inside the Sun. In its centre energy is released by nuclear fusion. Further out the energy travels through the radiative zone and further out still energy is transported by convection . The energy then reaches the surface and escapes to produce the light and heat we see and feel.

You can find out more about the inside of the Sun by diving beneath the solar surface.
