The Sun. Cutaway illustration showing the layers of the Sun. The Sun's core is a massive nuclear reactor where hydrogen atoms fuse to make helium atoms,releasing heat and light energy. The energy radiates to the outer layers and then rises to the surface by convection (white arrows). The Sun's visible surface,the photosphere (yellow),is affected by turbulent magnetic fields,causing phenomena like sunspots (cool areas,here coloured grey); solar prominences (eruptions of charged particles,upper left); and solar wind (where streams of particles escape into space (upper right). The faint outer atmosphere,the corona,extends millions of kilometres into space | |
