Cosmoscope
A living map of the solar system
Explore the Sun’s interior with an interactive 3D cutaway. See the fusion core, radiative zone and convection zone at representative relative sizes.
Remove a quarter of the Sun to explore how its energy moves outward from the fusion core through the radiative and convection zones.
Hydrogen fusion powers the Sun in its central core. Energy moves outward mainly by radiation through the radiative zone and by the motion of plasma in the convection zone.
The boundaries are representative values from solar structure models. Plasma textures, colours and animated circulation explain the layers; they are not photographs or measured views of the Sun’s hidden interior.
