Luminous objects emit their own light due to chemical reactions or heat. When this light enters our eyes, it stimulates the cells in our retinas, allowing us to see the object.
Luminous.
Luminous objects emit their own light, such as the sun or a light bulb, whereas non-luminous objects do not produce light but reflect light from other sources, like the moon or a table. Luminous objects are sources of light, while non-luminous objects only appear visible when light is shone upon them.
Non-luminous objects in space include planets, asteroids, comets, moons, and dust clouds. These objects do not emit their own light but instead reflect light from nearby stars or other luminous sources. They can be observed through telescopes or spacecraft.
Luminous objects are those that emit light of their own, such as the Sun, stars, and fireflies. They are sources of visible light due to processes like nuclear fusion or chemical reactions occurring within them.
