"Generate an image of a diagram illustrating the CNO cycle, a nuclear fusion process that occurs in the cores of stars more massive than the Sun, showing the catalytic cycle of carbon-12, nitrogen-14, and oxygen-16, with protons, helium nuclei, positrons, gamma rays, and neutrinos, set against a backdrop of a massive star's core, with a style that blends scientific accuracy and astrophysical context."
