What are some natural light sources?

The sun is the most important source of natural light, as the vast majority of the light we receive comes from it. The moon and stars are also sources of natural light.

Light is a form of energy that can be seen by the human eye. As well as natural sources, we also receive light from artificial or man-made sources. Burning wood, candles and animal fat are all ways of getting artificial light that have been used by humans for many years. In the modern era, light bulbs, fluorescent tubes, lasers and neon lights have also been used as artificial light sources.
