Natural Light Sources
* Stars: The most common natural light source. Stars produce light through nuclear fusion, a process where hydrogen atoms fuse to form helium, releasing immense energy in the form of light and heat. Our Sun is a star.
* Planets: While planets don't produce their own light, they reflect light from stars.
* Fireflies: These fascinating insects have a chemical reaction in their abdomens that creates a bioluminescent glow.
* Lightning: A spectacular natural electrical discharge that creates a bright flash of light.
* Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights): These breathtaking displays of light are caused by charged particles from the Sun interacting with the Earth's magnetic field.
Important Note: While the Moon appears to be a light source, it doesn't produce its own light. It simply reflects sunlight.
