How do stars generate heat and light
WebStars can be very different from each other—in color, brightness, temperature, size, and mass. For example, hot blue-white stars can reach 54,000°F (30,000°C) at their surface, ten times hotter than the coolest … WebAll stars generate energy deep within their cores by one of the most powerful processes in the Universe: nuclear fusion. Hydrogen nuclei smash together, forming helium and releasing huge amounts of energy. This is why a star shines. The pressure of the gas heated by fusion supports the star against its own gravity.
