Stars and Galaxies: Astronomy
Stars are massive, glowing balls of gas that produce light and heat through nuclear fusion. They come in various sizes and types, from small red dwarfs to enormous blue giants. Galaxies are vast collections of stars, gas, dust, and dark matter, organized into different shapes, such as spiral, elliptical, and irregular forms, with the Milky Way being one of the most well-known galaxies.
