Here are some examples of luminous objects:
* The Sun: Our star is the ultimate source of light for our solar system.
* Light bulbs: Incandescent, fluorescent, and LED bulbs all generate light.
* Fireflies: These insects produce light through a chemical reaction.
* Stars: Like our Sun, stars are massive balls of hot gas that emit light.
* Some living organisms: Certain jellyfish, deep-sea creatures, and bacteria can also produce light.
Objects that do not produce their own light but reflect light from other sources are called non-luminous objects. Examples include the moon, a table, and a book.
