The description you've provided refers to stars. Stars are massive celestial bodies composed primarily of hydrogen and helium gases. They produce light and heat through the process of nuclear fusion, which occurs in their cores. During fusion, hydrogen atoms combine under extreme pressure and temperature to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy is what makes stars shine and is critical for the existence of life on planets like Earth. Examples of stars include our Sun, as well as other stars in various stages of their life cycles, such as red giants, white dwarfs, and supernovae.

What are balls of gases that produce light and heat
The term "balls of gases that produce light and heat" refers to stars. Stars are massive celestial objects made up primarily of hydrogen and helium gases. They undergo nuclear fusion in their cores, which converts hydrogen into helium and releases vast amounts of energy. This energy is emitted in the form of light and heat, making stars visible from great distances in space.
The most well-known star is our Sun, which is a medium-sized star and the primary source of light and heat for Earth. Stars come in various types and sizes, including red dwarfs, giants, supergiants, and more, each with its own life cycle and characteristics.
